Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-κ2N3,O4)nickel(II) N,N-dimethylformamide disolvate

Abstract

In the title complex, [Ni(C8H9N2O4)2(H2O)2]·2C3H7NO, the NiII 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.
