Abstract

In the title complex, [Sm(NO₃)₃(C₃₀H₂₈N₂O₄)], the Sm atom is surrounded by ten O atoms. The (S,S)-2,2′-{[(1,2-diphenylethane-1,2-diyl)bis[(azaniumylylidene)methanylylidene]}bis(6-methoxyphenolate) ligand, obtained from o-vanillin and (1S,2S)-(−)-1,2-diphenylethylenediamine, exhibits a slightly distorted planar arrangement of the four coordinated O atoms. In the crystal, the complex shows intramolecular N—H⋯O hydrogen bonds and weak intermolecular C—H⋯O hydrogen bonds. The Hirshfeld surface analysis indicates that the most important contributions to the packing are from H⋯H (33.5%), O⋯H (34.1%) and C⋯H (21.7%) contacts.

Chemical context

Lanthanide metal complexes can have attractive functions such as magnetism and fluorescence when synthesized with properly designed ligands (Yao et al., 2019 ▸; Lin et al., 2009 ▸). In recent years, lanthanide complexes that act as single-molecule magnets (SMM) have received much attention (Then et al., 2015 ▸). In these complexes, distortion of the coordination geometry is an important factor for magnetic anisotropy and for the resulting SMM properties. However, the coordination chemistry of lanthanides is complicated, and it is necessary to prepare complexes with coordination environments suitable for the required properties. On the other hand, salen ligands are known to form stable chelate complexes with many metals (Cozzi et al., 2004 ▸). By incorporating a substituent group into salen ligands, it is possible to easily add more coordination sites and optical functionality such as the antenna effect that depend on intermolecular interactions and arrangements. Hence, functional lanthanide salen complexes have attracted attention (Ren et al., 2016 ▸). Accurate data such as bond angles and the geometry of coordination sites obtained based on crystal structure analysis and Hirshfeld surface analysis will be useful for the molecular design of new lanthanide and salen complexes. In this study, we prepared a new Sm^III–salen complex and report herein on its crystal structure and Hirshfeld surface analysis.

Structural commentary

The title Sm^III complex crystallizes in the monoclinic space group C2. The asymmetric unit contains two crystallographically independent molecules. This distorted prismatic [SmO₁₀] complex consists of three bidentate nitrate ions and two pairs of phenolate and methoxy groups of the salen ligand, which is slightly distorted from planar.

The bond distances between the metal center and ligating atoms range from 2.333 (5) to 2.373 (4) Å for the phenolato oxygen atoms, and from 2.606 (5) to 2.621 (6) Å for methoxy oxygen atoms. The bond lengths between the metal center and the nitrate oxygen atoms range from 2.475 (5) to 2.633 (5) Å, showing more flexibility than those of the Schiff base ligand. In the Schiff base ligand, the imine moieties are protonated to form iminium cations, but the C=N bond lengths remain close to those of normal imine bonds at 1.287 (8) and 1.30 (1) Å.

Intramolecular hydrogen bonds occur between the iminium protons and the phenolic oxygen atoms, with lengths of 1.71–1.89 Å (Table 1 ▸, Fig. 1 ▸). The bond distances and angles in the ligand are similar to those of analogous complexes (Hayashi et al., 2013 ▸).

Supramolecular features

Though some weak C—H⋯O intermolecular interactions are found (Table 1 ▸), no strong interactions such as O—H⋯O hydrogen bonds between molecules are observed in the crystal. Hirshfeld surface analysis (Spackman et al., 2009 ▸) was performed to investigate interactions in the crystal packing. Hirshfeld surfaces and fingerprint plots (McKinnon et al., 2004 ▸) were calculated using CrystalExplorer17.5 (Turner et al., 2017 ▸). Hydrogen bonds are strong interactions and they are indicated as red dots on the surface (Fig. 2 ▸) or two sharp spikes in the fingerprint plot (Fig. 3 ▸). ‘Wings’ in the fingerprint plots and diagonal plots at 1.8 Å are regarded as a characteristic feature potentially resulting from aromatic rings (Spackman et al., 2002 ▸)The contributions to the Hirshfeld surface are H⋯H (33.5%), O⋯H (34.1%) and C⋯H (21.7%) contacts.

Database survey

A search in the Cambridge Structural Database (CSD, Version 5.41, update of November 2019; Groom et al., 2016 ▸) for similar structures returned two relevant entries: (N,N′-ethane-1,2-diylbis{[2-(oxy)-3-(methoxy)phenyl]methaniminiumato})tris(nitrato)samarium (refcode MOLNEI; Yang et al., 2013 ▸) and (S,S)-{μ-[2,2′-{(1,2-diphenylethane-1,2-diyl)bis[(azanylylidene)methylylidene]}bis[6-(methoxy)phenolato]]}trinitratoeuropium(III)nickel(II) (JIWNEL; Mayans et al., 2019 ▸). In MOLNEI, a similar intramolecular N—H⋯O hydrogen bond is observed. Although the ligand of JIWNEL is similar to that in the title compound, the coordinating sites are filled with europium(III) and nickel(II) ions. For both MOLNEI and JIWNEL, the crystal packing is dominated by van der Waals interactions and C—H⋯O hydrogen bonds.

Synthesis and crystallization

(1S,2S)-(−)-1,2-Diphenylethylenediamine (0.100 g, 0.471 mmol) and o-vanillin (0.143 g, 0.940 mmol) were dissolved in ethanol (30 mL) and the resulting mixture was stirred at 313 K for 1 h to afford a yellow solution. To this solution, samarium nitrate hexahydrate (0.208 g, 0.468 mmol) was added and it was stirred at 313 K for 2 h. A yellow precipitate appeared immediately. The precipitate was filtered and washed with ethanol and hexane. The title compound (0.299 g, 0.366 mmol, yield 78.2%) was obtained as a yellow solid. IR (KBr, cm⁻¹) : 1624 (C=N double bond). Fluorescence bands in methanol solution were observed at 562 (⁴G_5/2 → ⁶H_5/2), 597 (⁴G_5/2 → ⁶H_7/2) and 644 (⁴G_5/2 → ⁶H _9/2) nm. Single crystals suitable for X-ray diffraction were obtained by recrystallization from methanol and diethyl ether (1:4, v/v) solution.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All C-bound H atoms were placed in geometrically calculated positions (C—H = 0.93–0.98 Å) and were constrained using a riding model with U _iso(H) = 1.2U _eq(C) or 1.5U _eq(C-methyl). SIMU, ISOR and AFIX 66 commands were used for C55, C56, C57, C58, C59, C60 to suppress temperature anisotropy and restrain bond lengths to appropriate values.

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.
