Diaquabis(5-carboxy-1H-imidazole-4-carboxylato-κ2N3,O4)iron(II)

Abstract

In the title compound, [Fe(C5H3N2O4)2(H2O)2], the FeII ion lies on an inversion centre and is coordinated by two N and two O atoms from two 5-carboxy-1H-imidazole-4-carboxylate ligands and two water molecules in a distorted octahedral geometry. An intramolecular O—H...O hydrogen bond occurs. In the crystal, intermolecular N—H...O and O—H...O hydrogen bonds form a three-dimensional network, which consolidates the packing.
