Bis(μ-3,5-dinitrosalicylato)hexaimidazoledicadmium(II) dihydrate

Abstract

The title dinuclear complex, [Cd2(C7H3N2O7)2(C3H4N2)6]·2H2O, lies about an inversion centre. Each CdII atom is coordinated by three O atoms from two 3,5-dinitro­salicylate ligands and the N atoms of three imidazole ligands. Three ligand O atoms and one N atom lie in the equatorial plane with the two other imidazole ligands axial in a distorted octa­hedral coordination environment. The intramolecular Cd⋯Cd separation is 3.906 (4) A. In the crystal structure, a supra­molecular network forms through extensive inter­molecular hydrogen-bonding inter­actions. One imidazole ring is disordered over two orientations in ratio of approximately 0.8:0.2.
