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

ABSTRACT: 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-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ate ligands and two water mol-ecules in a distorted octa-hedral 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 supra-molecular network is stabilized by intra- and inter-molecular N-H?O and O-H?O hydrogen bonds involving the ligands, coordinated water mol-ecules and dimethyl-formamide solvent mol-ecules.
