Abstract

In the title complex, [Ni(C16H13ClN2O3)(C3H4N2)], the NiII ion is coordinated by two O atoms and one N atom derived from the dianionic N'-[(1E)-1-(5-chloro-2-hy-droxy-phen-yl)ethyl-idene]-4-meth-oxy-benzohydrazide ligand and one N atom from the imidazole mol-ecule. The N2O2 donor set defines an approximate square-planar geometry. The dihedral angles between the imidazole ring and the fused six-membered and meth-oxy-benzene rings are 17.78 (14) and 13.23 (16)°, respectively; the dihedral angle between the C6 rings is 6.63 (12)°. The most prominent feature of the mol-ecular packing is the formation of 41-helical chains (along the c axis) mediated by imidazole-N-H⋯O(phenoxide) hydrogen bonding; these are linked by methyl-C-H⋯Cl inter-actions.
