title: Diaqua-bis-(4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ato-κN,O)zinc N,N-dimethyl-formamide disolvate.
abstract: In the title compound, [Zn(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·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-imid-azole-5-carboxyl-ato anions and two water O atoms in an octa-hedral environment, Each 4-carboxy-2-ethyl-1H-imid-azole-5-carboxyl-ato 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⋯O and O-H⋯O hydrogen bonds.
