{N′-[(E)-1-(5-Chloro-2-oxidophenyl)ethylidene]-4-methoxybenzohydrazidato-κ3 O,N′,O′}(1H-imidazole-κN 3)nickel(II)

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-hydroxyphenyl)ethylidene]-4-methoxybenzohydrazide ligand and one N atom from the imidazole molecule. The N2O2 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 C6 rings is 6.63 (12)°. The most prominent feature of the molecular 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 interactions.
