In the title compound, [Zn(C7H7N2O4)(2)(H2O)(2)]center dot 2C(3)H(7)NO, the Zn-II ion, which lies on a center of inversion, is coordinated by two O atoms and two N atoms from two 4-carboxy-2-ethyl-1H-imidazole-5-carboxylato anions and two water O atoms in an octahedral environment, Each 4-carboxy-2-ethyl-1H-imidazole-5-carboxylato ligand adopts a bidentate chelating mode to the Zn-II ion, forming two five-membered metalla rings. In the crystal, a two-dimensional framework parallel to (010) is formed by N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds.
