Abstract: The title dinuclear complex, [Cd₂(C₇H₃N₂O₇)₂(C₃H₄N₂)₆]·2H₂O, lies about an inversion centre. Each Cd^II 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 CdCd separation is 3.906 (4) Å. 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.
