Diaquabis(5-carboxy-2-methyl-1H-imidazole-4-carboxylato-kappa(2),N-3,O-4)cadmium(II)

In the title compound, [Cd(C6H7N2O5)(2)], the Cd atom lies on an inversion center and has a slightly distorted octahedral geometry. The equatorial plane contains two bidentate 5-carboxy- 2-methyl-1H-imidazole-4-carboxylate monoanionic ligands. Two coordinated water molecules occupy the axial sites. Intermolecular N - H (...) O hydrogen bonds link the molecules into chains, which are further connected by intermolecular O - H (...) O hydrogen bonds, resulting in a three-dimensional supramolecular framework.
