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

In the title complex, [Ni(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the Ni(II) atom is six-coordinated by two N,O-bidentate 5-carb­oxy-2-propyl-1H-imidazole-4-carboxyl­ate ligands and two water mol­ecules in a distorted octa­hedral environment. The methyl C and H atoms of the two ligands are disordered over two sets of sites in 0.74 (2):0.26 (2) and 0.57 (8):0.43 (8) ratios. A supra­molecular network is stabilized by intra- and inter­molecular N—H⋯O and O—H⋯O hydrogen bonds involving the ligands, coordinated water mol­ecules and dimethyl­formamide solvent mol­ecules.
