(2-{[2-(4-Chlorophenoxy)-1-oxidoethylidene-κO1]hydrazonomethyl}phenolato-κ2N1,O)(1H-imidazole-κN3)nickel(II)

In the title complex, [Ni(C15H11ClN2O3)(C3H4N2)], the NiII ion is coordinated by a phenolate O, hydrazine N and carbonyl O atom from the hydrazone ligand and by an N atom from the imidazole molecule, forming a distorted square-planar geometry. Intermolecular N—H...N hydrogen bonds link neighboring molecules into extended chains parallel to [100].
