Diaqua-bis-(4-carb-oxy-2-propyl-1H-imidazole-5-carboxyl-ato-κN,O)copper(II) N,N-dimethyl-formamide disolvate

In the title complex, [Cu(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the Cu(II) ion, lying on an inversion center, is six-coordinated in a slightly distorted octa-hedral geometry. Two N atoms and two O atoms from two H(2)pimda (H(3)pimda is 2-propyl-1H-4,5-dicarb-oxy-lic acid) ligands are in the equatorial plane. The axial positions are occupied by two O atoms from two water mol-ecules. A two-dimensional supra-molecular network parallel to (001) is constructed by N-H⋯O and O-H⋯O hydrogen bonds. An intra-molecular O-H⋯O hydrogen bond is also observed.
