trans-Diaquabis[4-carboxy-5-carboxylato-2-(pyridin-1-ium-4-yl)-1H-imidazol-1-ido-κ2N1,O5]cobalt(II)

Abstract

In the title compound, [Co(C10H6N3O4)2(H2O)2], the CoII ion is coordinated by two O atoms of two water molecules, two imidazole nitrogen atoms and two carboxylate O atoms of the two trans-standing chelate ligands, displaying a distorted octahedral coordination geometry. A three-dimensional supramolecular framework is generated through N—H...O, O—H...N and O—H...O hydrogen-bonding interactions.
