Abstract

In the title compound, C₃₈H₂₈O₆, the dihedral angles between the naphthalene ring system and its pendant benz­yloxy rings A and B are 88.05 (7) and 80.84 (7)°, respectively. The dihedral angles between the A and B rings and their attached phenyl rings are 49.15 (8) and 80.78 (8)°, respectively. In the extended structure, the mol­ecules are linked by weak C—H⋯O and C—H⋯π hydrogen bonds, and π–π stacking inter­actions, which variously generate C(11) chains and R ₂ ²(12) loops as part of a three-dimensional network. The Hirshfeld surface [fingerprint contributions = H⋯H (42.3%), C⋯H/H⋯C (40.3%) and O⋯H/H⋯O (15.7%)] and inter­molecular inter­action energies are reported, with dispersion (E _dis = −428.6 kJ mol⁻¹) being the major contributor.

1. Chemical context

Naphthalene, biphenyl or benzene rings can act as rigid cores in liquid crystal mol­ecules. A variety of banana-shaped, bow-shaped or bent-core ferroelectric liquid crystals were developed by incorporating a benzene ring as a rigid core (Noiri et al., 1996 ▸; Srinivasa et al., 2017 ▸). These types of compounds form lamellar and/or columnar mesophases (Szydlowska et al., 2003 ▸) and they have been subjected to experimental and theoretical studies (Reddy et al., 2006 ▸; Vaupotič, 2006 ▸). Liquid crystalline materials with a bent-core mol­ecule are attractive because they exhibit good physical properties and possess two-dimensional smectic phases that display qualitatively different physical properties than calamatic ferroelectric liquid crystals.

Our team is studying new bent-core liquid crystals with naphthalene rings as a rigid core (Srinivasa et al., 2018 ▸) and, as part of that work, we have performed a simple coupling reaction between 1,2-di­hydroxy­naphthalene and 3-benz­yl­oxybenzoic acid to construct the title mol­ecule. It is a bent-type non-liquid crystal material, possibly due to the absence of alkyl chains/polar moiety at the ends of the mol­ecule.

2. Structural commentary

The title compound crystallizes with one mol­ecule in the asym­metric unit (Fig. 1 ▸) in the space group P2₁/n. The dihedral angles between the C1–C10 naphthalene ring system (r.m.s. deviation = 0.022 Å) and its pendant C26–C31 (A) and C12–C17 (B) benz­yloxy rings are 88.05 (7) and 80.84 (7)°, respectively. The dihedral angles between the A and B rings and their attached C33–C38 and C19–C24 phenyl rings are 49.15 (8) and 80.78 (8)°, respectively. Key torsion angles include C1—O4—C25—C26 [−160.98 (13)°], C28—O2—C32—C33 [−172.04 (14)°], C10—O1—C11—C12 [−168.94 (14)°] and C14—O3—C18—C19 [172.84 (14)°]. Otherwise, the geometrical data for the title compound may be regarded as normal.

3. Supra­molecular features

In the crystal, the mol­ecules are linked by numerous C—H⋯O and C—H⋯π inter­actions (Table 1 ▸). Prominent packing features include a C(11) chain (arising from the C21—H21⋯O2ⁱⁱ hydrogen bond), which runs along [010], and centrosymmetric (12) loops (arising from the C9—H9⋯O5ⁱ hydrogen bond) between the mol­ecules as shown in Fig. 2 ▸. These, and the C—H⋯π inter­actions, link the mol­ecules into a three-dimensional network (see Figs. S1 and S2 in the supporting information).

4. Hirshfeld surface analysis

The title mol­ecule was subjected to Hirshfeld surface analysis (Spackman & Jayatilaka, 2009 ▸) and the two-dimensional (2D) fingerprint plots (McKinnon et al., 2007 ▸) were generated with CrystalExplorer17 (Turner et al., 2017 ▸). The Hirshfeld surface mapped on d _norm is shown in Fig. 3 ▸ and the overall 2D fingerprint plot and those delineated into H⋯H (42.3%), C⋯H/H⋯C (40.3%) and O⋯H/H⋯O (15.7%) contacts, together with their relative contributions to the Hirshfeld surface, are illustrated in Fig. 4 ▸. The inter­action energies for the title compound were calculated at the HF/3-21G quantum level of theory in CrystalExplorer. The four energy variables that make up the total inter­molecular inter­action energy (E _tot) are electrostatic (E _ele), polarization (E _pol), dispersion (E _disp) and exchange–repulsion (E _rep), and the cylinder-shaped energy frameworks represent the relative strengths of the inter­action energies in individual directions, as well as the topologies of pairwise inter­molecular inter­action energies within the crystal (Mackenzie et al., 2017 ▸). The energies between mol­ecular pairs are depicted as cylinders connecting the centroids of two mol­ecules, with the radius of the cylinder equal to the amount of inter­action energy between the mol­ecules (Wu et al., 2020 ▸). The net inter­action energies for the title compound are E _ele = −56.3 kJ mol⁻¹, E _pol = −30.4.0 kJ mol⁻¹, E _dis = −428.6 kJ mol⁻¹ and E _rep = 160.4 kJ mol⁻¹, with a total inter­action energy E _tot of −333.3 kJ mol⁻¹. Therefore, E _dis is the major inter­action energy in the title compound. The energy framework showing the electrostatic potential force, dispersion force and total energy diagrams are shown in Fig. 5 ▸. The cylindrical radii are proportional to the relative strength of the corresponding energies and they were adjusted to the same scale factor of 50 with a cutoff value of 5 kJ mol⁻¹.

5. Database survey

A search of the Cambridge Structural Database (CSD; Version 5.43, update of March 2022: Groom et al., 2016 ▸) for the naphthalene-2,3-diyl fragment gave 26 hits, of which six mol­ecules are similar to the title compound, with CSD refcodes WAFRII, WAFROO, WAFRUU, WAFSAB, WAFSEF and WAFSIJ (Rutherford et al., 2020 ▸). There exist inter­molecular inter­actions dominated by π–π stacking and C—H⋯π inter­actions involving the arene rings in the benzoate fragments and the arene ring in the tetra­hydro­napthalene moiety. A ‘thermosalient phase transition effect’ was studied in the compounds coded QIBMUM and QIBMUM01–QIBMUM06 (Tamboli et al., 2013 ▸), which feature a naphthalene-2,3-diyl bis­(4-fluoro­benzoate) fragment. The presence of π–π stacking and C—H⋯O and C—H⋯F inter­actions appear to play an important role in determining the mol­ecular conformations. The crystal structure analyses of the polymorphic structures coded DOPPAB, DOPPAB01, DOPPAB02, DOPPOP, DOPPOP01 and DOPQAC (Tamboli et al., 2018 ▸) revealed weak inter­molecular inter­actions, such as C—H⋯O, C—H⋯π and π–π stacking, as also seen in the title mol­ecule. These inter­actions are actively involved in mol­ecular aggregation, which results in the polymorphic modifications, if they are subjected to thermal transformation. Here, all the mol­ecules crystallize in the space group Pbcn or P2/c. The crystal structure analyses of IJAGIJ01 to IJAGIJ05 (Tamboli et al., 2014 ▸) are polymorphs of isomeric napthalene-2,3-diol ditoluates, in which the inter­molecular inter­actions, such as C—H⋯O, C—H⋯π and π–π stacking, are similar to the inter­actions present in the title mol­ecule.

6. Synthesis and crystalization

Under an inert atmosphere, 1,2-di­hydroxy­naphthalene (1.00 mmol), a catalytic amount of 4-di­methyl­amino­pyridine and 3-benzyl­oxybenzoic acid (2.00 mmol) were dissolved in 50 ml of dry di­chloro­methane (DCM). The above mixture was stirred for 2 h at room temperature with a solution of N,N-di­cyclo­hexyl­carbodi­imide (1.2 mmol) in DCM (20 ml). Filtration was used to remove the precipitated N,N-di­cyclo­hexyl­urea and the solvent was evaporated. To obtain the pure product, the solid residue was purified using column chromatography on silica gel with DCM as an eluent, followed by recrystallization from ethyl alcohol solution.

Special details

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.
