{N′-[(E)-1-(5-Chloro-2-oxidophen­yl)ethyl­idene]-4-meth­oxy­benzohydrazidato-κ(3) O,N′,O′}(1H-imidazole-κN (3))nickel(II)

In the title complex, [Ni(C(16)H(13)ClN(2)O(3))(C(3)H(4)N(2))], the Ni(II) ion is coordinated by two O atoms and one N atom derived from the dianionic N′-[(1E)-1-(5-chloro-2-hy­droxy­phen­yl)ethyl­idene]-4-meth­oxy­benzohydrazide ligand and one N atom from the imidazole mol­ecule. The N(2)O(2) donor set defines an approximate square-planar geometry. The dihedral angles between the imidazole ring and the fused six-membered and meth­oxy­benzene rings are 17.78 (14) and 13.23 (16)°, respectively; the dihedral angle between the C(6) rings is 6.63 (12)°. The most prominent feature of the mol­ecular packing is the formation of 4(1)-helical chains (along the c axis) mediated by imidazole-N—H⋯O(phenoxide) hydrogen bonding; these are linked by methyl-C—H⋯Cl inter­actions.
