The asymmetric unit of title complex, [Ni(C20H13BrN2O2)(C5H5N)], contains two independent molecules. In each molecule, the central NiII atom has a square-planar environment, formed by the tridentate hydrazone and the monodentate pyridine ligands, with the N atoms in a trans arrangement about the NiII atom.
