Crystal structure of bis[2-(1H-benzimidazol-2-yl-κN3)aniline-κN]bis(nitrato-κO)cadmium(II)

Abstract

In the title compound, [Cd(NO3)2(C13H11N3)2], the CdII atom lies on a twofold rotation axis and is coordinated by four N atoms and two O atoms, provided by two bidentate 2-(1H-benzimidazol-2-yl)aniline ligands, and two nitrato O atoms, forming a distorted octahedral geometry [range of bond angles around the Cd atom = 73.82 (2)–106.95 (8)°]. In the ligand, the dihedral angle between the aniline ring and the benzimidazole ring system is 30.43 (7)°. The discrete complex molecule is stabilized by an intramolecular N—H...O hydrogen bond. In the crystal, intermolecular N—H...O hydrogen bonds link the molecules, forming a three-dimensional network.
