Diaquabis(1H-imidazole-4,5-dicarboxylato-κN3)cobalt(II)N,N-dimethylformamide disolvate

Abstract

In the title compound, [Co(C5H3O4)2(H2O)2]·2C3H7NO, the octahedrally coordinated CoII atom lies on an inversion centre. The equatorial plane of the octahedron comprises two bidentate 1H-imidazole-4,5-di­carboxyl­ate monoanions, coordinated through the N-3 atoms, and one carboxyl­ate O atom, with two water mol­ecules in the axial coordination sites. A one-dimensional chain structure is formed by intermolecular hydrogen bonds in the equatorial plane, between the uncoordinated N atom in the imidazole ring and an uncoordinated carboxyl O atom. The two O atoms of the coordinated water mol­ecules in each chain are engaged in two hydrogen bonds with the uncoordinated carboxyl O atoms of two adjacent chains, forming a two-dimensional network structure.
