Crystal structure and Hirshfeld surface analysis of aqua­(1,10-phenanthroline-κ²N,N′)bis­[3-(2-sulf­an­yl­idene-2,3-di­hydro-1,3-benzoxazol-3-yl)propano­ato-κO]zinc(II) monohydrate

The crystal structure of a zinc(II) complex containing 3-(2-sulfanylidene-2,3-di­hydro-1,3-benzoxazol-3-yl)propano­ate and 1,10-phenanthroline ligands is described, together with its supra­molecular features and Hirshfeld surface analysis.

Abstract

The crystal structure of the title compound, [Zn(C₁₀H₈NO₃S)₂(C₁₂H₈N₂)(H₂O)]·H₂O, is reported together with an analysis of its inter­molecular inter­actions. The Zn^II ion is five-coordinate, being bonded to two monodentate carboxyl­ate O atoms from two crystallographically independent 3-(2-sulfanylidene-2,3-di­hydro-1,3-benzoxazol-3-yl)propano­ate ligands, two N atoms of a chelating 1,10-phenanthroline ligand and one water O atom. The coordination geometry is distorted square-pyramidal (τ₅ ≃ 0.30). Although the two carboxyl­ate ligands adopt the same κO coordination mode, they differ in their Zn—O bond lengths and in the conformations of their propano­ate chains. In the crystal, O—H⋯O hydrogen bonds involving the coordinated and solvent water mol­ecules link the complexes into one-dimensional ribbons parallel to [100], reinforced by C—H⋯O and C—H⋯S contacts. Additional consolidation is provided by π–π stacking inter­actions involving the phenanthroline and benzoxazoline-derived aromatic rings. Hirshfeld surface analysis shows that H⋯H (42.0%), H⋯O/O⋯H (19.1%), H⋯S/S⋯H (13.7%) and H⋯C/C⋯H (11.9%) contacts dominate the inter­molecular surface, while C⋯C contacts (5.8%) are consistent with the observed π–π stacking.

1. Chemical context

Heterocyclic compounds containing N, O and S atoms are of considerable inter­est because their diverse donor properties make them useful in coordination chemistry and in the design of biologically active compounds (Contreras et al., 2009 ▸). Benzoxazolin-2-one and benzoxazolin-2-thione derivatives form an important class of such compounds, and substitution at the ring N atom provides a convenient means of modifying their physicochemical and biological properties. Derivatives of these heterocycles have been reported to exhibit anti­cancer, analgesic, anti-inflammatory and neuroprotective activities (Prasher et al., 2023 ▸). In particular, sulfur-containing benzoxazole derivatives are of inter­est because replacement of the carbonyl O atom by S increases the polarizability of the heterocycle and may influence both metal-ion inter­actions and inter­molecular contacts. The ability of this sulfur-containing system to inter­act with Zn centres is illustrated by the inhibition of human carbonic anhydrase II by 2-mercaptobenzoxazole, for which coordination of the S atom to the catalytic Zn ion has been demonstrated crystallographically (Bozdag et al., 2020 ▸).

The ligand used in the present study, 3-(2-sulfanylidene-2,3-di­hydro-1,3-benzoxazol-3-yl)propanoic acid, combines a carb­oxy­lic acid group capable of metal coordination with a benzoxazole-2-thione fragment that can participate in supra­molecular inter­actions. The crystal structure of the free acid and those of its mono­ethano­lammonium and ethyl­enedi­ammonium salts have previously been reported (Ashurov et al., 2017a ▸). In combination with this ligand, 1,10-phenanthroline provides a rigid chelating N,N′-donor environment and an extended aromatic surface that may contribute to the consolidation of the coordination unit and to π-related inter­molecular inter­actions (Sammes & Yahioglu, 1994 ▸).

In this work, we report the synthesis, crystal structure and Hirshfeld surface analysis of the title compound (I). The structural analysis focuses on the coordination environment of the Zn^II ion and on the inter­molecular inter­actions responsible for the crystal packing.

2. Structural commentary

The asymmetric unit of the title compound, [Zn(NBA)₂(phen)(H₂O)]·H₂O, where NBA denotes the 3-(2-sulfanylidene-2,3-di­hydro-1,3-benzoxazol-3-yl)propano­ate anion and phen is 1,10-phenanthroline, comprises one neutral Zn^II complex mol­ecule and one water mol­ecule of crystallization (Fig. 1 ▸). The two crystallographically independent NBA ligands are distinguished by the suffixes A and B. The phen ligand is represented by atoms N1, N2 and C1–C12, while O1W and O2W correspond to the coordinated and solvent water mol­ecules, respectively.

Figure 1.

The Zn1 atom is five-coordinate, being bonded to one carboxyl­ate O atom from each of the two independent NBA ligands (O2A and O2B), the two N atoms of the chelating phen ligand (N1 and N2), and the O atom of the coordinated water mol­ecule O1W. The Zn–donor bond lengths are Zn1—O2A = 1.9682 (15), Zn1—O2B = 2.0457 (17), Zn1—N2 = 2.092 (18), Zn1—O1W = 2.133 (2) and Zn1—N1 = 2.1729 (19) Å. Thus, both NBA ligands adopt the same monodentate κO coordination mode, although the Zn1—O2A bond is shorter than Zn1—O2B by ca 0.078 Å.

In both NBA ligands, the second carboxyl­ate O atom lies outside the primary coordination sphere. The Zn1⋯O3A and Zn1⋯O3B separations are 3.0871 (19) and 2.6375 (18) Å, respectively. The shorter Zn1⋯O3B separation may be regarded as a secondary contact, but it is substanti­ally longer than the normal Zn1—O2B coordination bond and is not included in the primary coordination number. The corresponding carboxyl­ate C—O distances are O2A—C10A = 1.282 (3) and O3A—C10A = 1.224 (3) Å for ligand A, and O2B—C10B = 1.285 (3) and O3B—C10B = 1.231 (3) Å for ligand B.

The phen ligand acts as a conventional chelating κ²N,N′ donor. The Zn1—N1 and Zn1—N2 bond lengths are 2.1729 (19) and 2.0982 (18) Å, respectively, and the N1—Zn1—N2 bite angle is 78.10 (7)°. Coordination generates a five-membered Zn1/N1/C12/C11/N2 chelate ring, while the fused phenanthroline framework remains essentially planar.

The five-coordinate geometry around Zn1 is strongly distorted. The two largest coordination angles are O1W—Zn1—N1 = 161.44 (7)° and O2B—Zn1—N2 = 143.68 (7)°. These values give an Addison parameter τ₅ = (β - α)/60 of 0.30, indicating that the coordination geometry is substanti­ally closer to the square-pyramidal limit (τ₅ = 0) than to the trigonal-bipyramidal limit (τ₅ = 1). The Zn^II centre is therefore best described as having a distorted square-pyramidal five-coordinate environment.

Although the two crystallographically independent NBA ligands have the same κO coordination mode, they differ in both the Zn—O bond lengths and the conformations of their N-substituted propano­ate chains. Their benzoxazoline-2-thione ring systems are essentially planar and the C=S bond lengths are very similar [S1A—C7A = 1.647 (2) and S1B—C7B = 1.644 (2) Å]. The conformational differences are reflected in the C1A—N1A—C8A—C9A and C1B—N1B—C8B—C9B torsion angles of −92.4 (2) and −112.2 (2)°, respectively, and are particularly pronounced in the N1A—C8A—C9A—C10A and N1B—C8B—C9B—C10B torsion angles of −179.54 (18) and 61.4 (3)°, respectively. Thus, the two NBA ligands retain the same mode of coordination to Zn^II but adopt distinctly different conformations in the crystal.

3. Supra­molecular features

The crystal packing is dominated by a cooperative water-mediated O—H⋯O hydrogen-bonding network (Table 1 ▸) involving the coordinated water mol­ecule O1W, the water mol­ecule of crystallization O2W and the carboxyl­ate O atoms O2A and O2B (Fig. 2 ▸). The coordinated water mol­ecule acts as a double donor through O1W—H1WA⋯O2Wⁱ [H⋯A = 1.95 (3) Å, D⋯A = 2.749 (3) Å and D—H⋯A = 155 (3)°] and O1W—H1WB⋯O2Bⁱ [1.94 (3), 2.751 (3) Å and 159 (3)°, respectively], where symmetry code (i) is −x, 1 − y, 1 − z. The water mol­ecule of crystallization donates through O2W—H2WA⋯O2A [H⋯A = 1.96 Å, D⋯A = 2.797 (3) Å and D—H⋯A = 170°] and O2W—H2WB⋯O2Bⁱⁱ [2.46, 3.245 (3) Å and 154°, respectively; symmetry code: (ii) 1 − x, 1 − y, 1 − z]. These inter­actions link the complex mol­ecules and water mol­ecules of crystallization into fused cyclic motifs, generating a one-dimensional hydrogen-bonded ribbon parallel to [100] (Figs. 2 ▸ and 3 ▸). The ribbon is reinforced by the nearly linear C1—H1⋯O2Wⁱⁱ inter­action [H⋯A = 2.39 Å, D⋯A = 3.319 (4) Å and D—H⋯A = 178°] and by the inter­molecular C8A—H8AB⋯S1Aⁱⁱⁱ contact [H⋯A = 2.87 Å, D⋯A = 3.716 (2) Å and D—H⋯A = 146°; symmetry code: (iii) x − 1, y, z], the latter also propagating along [100].

Offset π–π stacking inter­actions provide a further contribution to the crystal packing (Fig. 3 ▸). For the phen ligand, Cg5 and Cg6 are the centroids of the N1/C1–C4/C12 and N2/C7–C11 rings, respectively. The translational Cg5⋯Cg6^iv inter­action [symmetry code: (iv) 1 + x, y, z] has a centroid–centroid distance of 3.9453 (15) Å, an inter­planar angle of 3.49 (12)° and a slippage of 1.921 Å; the corresponding perpendicular separations are 3.5263 (10) and 3.4460 (11) Å. Ligand A participates in two inversion-related π–π contacts. The Cg7⋯Cg7^v inter­action, where Cg7 is the centroid of the C1A–C6A benzene ring, has a centroid–centroid distance of 3.5541 (15) Å and a slippage of 1.304 Å. A second contact, Cg3⋯Cg7^v, occurs at 3.7201 (14) Å with a slippage of 1.722 Å, where Cg3 is the centroid of the O1A/C6A/C1A/N1A/C7A heterocyclic ring. Both contacts involve symmetry code (v), 1 − x, 2 − y, 2 − z. Ligand B displays a different π–π stacking arrangement. The shortest contact is Cg4⋯Cg8^vi = 3.5381 (13) Å, where Cg4 and Cg8 are the centroids of the O1B/C6B/C1B/N1B/C7B and C1B–C6B rings, respectively. This inter­action has an inter­planar angle of 2.41 (12)° and a small slippage of 0.855 Å. A second benzene–benzene inter­action, Cg8⋯Cg8^vi, occurs at 3.6998 (14) Å with a slippage of 1.373 Å [symmetry code: (vi) −x, 1 − y, −z]. Thus, ligand A exhibits the shorter benzene–benzene stacking contact, whereas the heterocycle–benzene contact involving ligand B shows the more direct overlap. Together with the hydrogen-bonding network, these π–π inter­actions consolidate the crystal packing.

4. Hirshfeld surface analysis

To qu­antify the inter­molecular contacts contributing to the crystal packing, a Hirshfeld surface analysis (Spackman & Jayatilaka, 2009 ▸) was performed using CrystalExplorer17 (Turner et al., 2017 ▸). The percentage contributions of the different contact types are summarized in Fig. 4 ▸, while the two-dimensional fingerprint plots and corresponding filtered Hirshfeld surface views are shown in Fig. 5 ▸. H⋯H contacts make the largest contribution, accounting for 42.0% of the total surface. The next most important contributions are H⋯O/O⋯H (19.1%), H⋯S/S⋯H (13.7%) and C⋯C (5.8%) contacts.

The H⋯O/O⋯H contacts are associated with the O—H⋯O and C—H⋯O inter­actions described in the supra­molecular analysis (Table 1 ▸). These short contacts appear as intense red regions on the Hirshfeld surface mapped over d_norm (Fig. 6 ▸). The appreciable H⋯S/S⋯H contribution is likewise consistent with the observed C—H⋯S inter­actions. Taken together, the H⋯O/O⋯H and H⋯S/S⋯H contacts account for 32.8% of the Hirshfeld surface, emphasizing the importance of hydrogen-bonding and related directional contacts in the crystal packing. C⋯C contacts contribute 5.8% of the surface and are consistent with the π–π stacking inter­actions identified crystallographically, including the phenanthroline and benzoxazoline-derived aromatic stacks discussed above (Figs. 3 ▸ and 7 ▸). Smaller contributions arise from C⋯S/S⋯C (2.7%), O⋯O (1.2%), H⋯N/N⋯H (1.0%), C⋯N/N⋯C (1.0%), O⋯S/S⋯O (0.8%), C⋯O/O⋯C (0.4%) and N⋯S/S⋯N (0.2%) contacts. Overall, the Hirshfeld surface analysis confirms that hydrogen-based contacts dominate the inter­molecular association, while the measurable C⋯C contribution provides additional support for the aromatic π–π stacking that consolidates the crystal structure.

5. Database survey

A search of the Cambridge Structural Database (CSD, Version 6.01, November 2025, including the February 2026 updates; Groom et al., 2016 ▸) for the benzoxazole-derived fragment of the ligand used here yielded 215 hits. The most relevant are the free acid YEDCOC and its mono­ethano­lammonium and ethyl­enedi­ammonium salts, YEDCUI and YEDDAP (Ashurov et al., 2017a ▸), the related Zn^II complex [Zn(L)₂(H₂O)₄] (UNODOR; Ashurov et al., 2011 ▸) and its isostructural Co^II/Cu^II analogues (Ashurov et al., 2014 ▸), the (2-oxo-1,3-benzoxazol-3(2H)-yl)acetate derivatives NUZSIM (Wang et al., 2016 ▸) with polymorphs NUZSIM01/NUZSIM02 (Ashurov et al., 2017b ▸) and the solvate, salts and hydrate ULIBUO, ULICAV, ULICAV01 and ULICOJ (Ashurov et al., 2015b ▸), and related tri­ethano­lamine mixed-ligand carboxyl­ate complexes of Zn^II, Cd^II and Cu^II (Ashurov et al., 2015a ▸, 2016a ▸,b ▸). No entry corresponding to a Zn^II complex of this thione-containing propano­ate ligand together with 1,10-phenanthroline was found.

A further search for the [Zn(phen)(κO-RCOO)₂(H₂O)] fragment – a chelating phen ligand, two monodentate carboxyl­ates and one aqua ligand, as found here – retrieved 61 hits, confirming that this five-coordinate geometry is well established for Zn^II, even though it has not previously been combined with the present thione-containing ligand. To compare parameters rather than connectivity alone, the Zn—donor bond lengths of the title compound may be set against four representative examples: ADUROH (Luo et al., 2007 ▸), QAHNUK (Liu et al., 2011 ▸), ETUXAT (Nie et al., 2011 ▸) and BUBYOO (Huang et al., 2014 ▸), the last of which, like the title compound, crystallizes with an additional water mol­ecule of crystallization. The Zn1—O(carboxyl­ate) bond lengths in the title compound [1.9682 (15) and 2.0457 (17) Å] compare closely with those in the four analogues [1.988 (3)/2.055 (2), 1.968 (2)/2.000 (2), 2.015 (2)/2.032 (2) and 1.997 (2)/2.064 (2) Å, respectively, in the order above]. Similarly, the Zn1—O(aqua) distance of the title compound [2.133 (2) Å] lies close to the corresponding values [2.030 (3), 2.128 (2), 2.110 (3) and 2.107 (2) Å], and the two Zn1—N(phen) distances [2.098 (2) and 2.173 (2) Å] are comparable with those in the same four structures [2.087 (4)/2.194 (3), 2.103 (2)/2.184 (2), 2.126 (3)/2.131 (2) and 2.095 (2)/2.163 (2) Å]. In every case, including the title compound, the two symmetry-independent Zn—O(carboxyl­ate) bonds are slightly inequivalent [Δ = 0.078 Å in the title compound, versus 0.067, 0.032, 0.017 and 0.067 Å in the four analogues, respectively], showing that this small asymmetry is a general feature of bis­(monodentate-carboxyl­ato) coordination at Zn^II rather than a peculiarity of the title compound.

6. Synthesis and crystallization

Zinc chloride dihydrate, 3-(2-sulfanylidene-2,3-di­hydro-1,3-benzoxazol-3-yl)propanoic acid (HNBA) and 1,10-phenanthroline were mixed in a 1:2:1 molar ratio. An aqueous solution of ZnCl₂·2H₂O (0.10 mmol, 17.2 mg) in 5 mL of distilled water was stirred while an ethano­lic solution containing the two organic ligands was added dropwise over approximately 15 min. The ligand solution was prepared by dissolving HNBA (0.20 mmol, 44.7 mg) in 6 mL of warm ethanol, followed by the addition of 1,10-phenanthroline (0.10 mmol, 18.0 mg), dissolved in 4 mL of ethanol. The resulting clear, colourless solution was stirred for a further 30 min at room temperature and then filtered through a fine-porosity glass frit. The filtrate was left to evaporate slowly at room temperature. Colourless single crystals suitable for X-ray diffraction were obtained, collected by filtration, washed with a small amount of cold ethanol–water (1:1, v/v), and air-dried. The isolated yield was approximately 65% based on Zn. Analysis calculated for C₃₂H₂₈N₄O₈S₂Zn: C 52.93, H 3.89, N 7.72, S 8.83%. Found: C 52.88, H 3.81, N 7.66, S 8.78%.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. H atoms bonded to C atoms were placed in geometrically calculated positions and refined using a riding model, with C—H distances of 0.93 Å for aromatic H atoms and 0.97 Å for methyl­ene H atoms. The H atoms of the coordinated water mol­ecule O1W (H1WA and H1WB) were located from difference-Fourier maps and refined with restrained O—H distances, giving O1W—H1WA = 0.85 (3) and O1W—H1WB = 0.86 (3) Å. The H atoms of the water mol­ecule of crystallization O2W (H2WA and H2WB) were retained at fixed positions with O—H = 0.85 Å. Two least-squares restraints were used in the final refinement.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
