Diaqua-bis-(1H-imidazole-κN(3))bis-(4-nitro-benzoato-κO(1))cadmium

Abstract

In the centrosymmetric title compound, [Cd(C(7)H(4)NO(4))(2)(C(3)H(4)N(2))(2)(H(2)O)(2)], the Cd(II) atom, located on an inversion center, is coordinated by two N atoms and four O atoms in an octa-hedral geometry. The inter-nal cohesion of the mol-ecule is enhanced by an intra-molecular O-H⋯O hydrogen bond. Inter-molecular O-H⋯O and C-H⋯O hydrogen bonds and π-π contacts [centroid-centroid distance = 3.6549 (2) Å] define two-dimensional networks parallel to (001), which are further connected by weaker C-H⋯O inter-actions into a weakly connected three-dimensional supra-molecular framework.
