Abstract

In the title compound, [Fe(C(5)H(3)N(2)O(4))(2)(H(2)O)(2)], the Fe(II) ion lies on an inversion centre and is coordinated by two N and two O atoms from two 5-carb-oxy-1H-imidazole-4-carboxyl-ate ligands and two water mol-ecules in a distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds form a three-dimensional network, which consolidates the packing.
