Diaqua­bis­(4-carb­oxy-2-propyl-1H-imidazole-5-carboxyl­ato-κ(2) N (3),O (4))zinc(II) N,N-dimethyl­formamide disolvate

In the crystal structure of the title compound, [Zn(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the Zn(II) atom is coordinated by two N,O-bidentate 2-propyl-1H-imidazole-4,5-dicarboxyl­ate anions and two water mol­ecules in a distorted octa­hedral environment. The asymmetric unit consists of one Zn(II) atom located on a center of inversion as well as one anion, one water mol­ecule and one additional dimethyl­formamide mol­ecule that occupy general positions. Between the carboxyl and the carboxyl­ate group an intra­molecular hydrogen bond is found in which the hydroxy H atom is disordered. Disorder is also found for the H atoms of one of the three methyl groups. In the crystal structure, additional inter­molecular N—H⋯O and O—H⋯O hydrogen bonding is found.
