2N3,O4)cobalt(II) dimethylformamide disolvateAbstract: In the title compound, [Co(C6H5N2O4)2(H2O)2]·2C3H7NO, the CoII ion lies on an inversion center and adopts a slightly distorted CoN2O4 octahedral geometry binding two bidentate chelating 5-carboxy-2-methyl-1H-imidazole-4-carboxylate (H2MIDA-) monoanionic ligands and two axial aqua ligands. In the crystal structure, intermolecular O-H
O hydrogen bonds link neighboring molecules, generating a two-dimensional framework containing eight-membered H4O4 rings. In addition, the dimethylformamide solvent molecules are hydrogen bonded to the two-dimensional framework via the NH groups of the H2MIDA- ligands.
