{N'-[(E)-(5-Bromo-2-oxidophen-yl)(phenyl)-methyl-ene]-4-chloro-benzo-hydrazidato}pyridine-nickel(II).

ABSTRACT: The asymmetric unit of title complex, [Ni(C(20)H(12)BrClN(2)O(2))(C(5)H(5)N)], contains one complex with the central Ni atom in a slightly distorted square-planar environment, formed by the tridentate hydrazone and the monodentate pyridine ligands, with N atoms in a trans arrangement about the Ni atom.
