Crystal structure and Hirshfeld surface analysis of ((S,S)-2,2′-{[(1,2-di­phenyl­ethane-1,2-di­yl)bis­[(aza­n­ium­ylyl­idene)methanylyl­idene]}bis­(6-meth­oxy­phenolato))trinitratosamarium(III)

In the title complex, [Sm(NO(3))(3)(C(30)H(28)N(2)O(4))], 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.
