Square-planar and octahedral nickel complexes of an acylhydrazone ligand and the serendipitous isolation of a potential octahedral nickel acylhydrazone precursor

Abstract

An investigation of the coordination chemistry of the ((E)-N′-(4-hydroxybenzylidene)-4-hydroxybenzohydrazide) Schiff-based ligand (HL) towards Ni(ii) acetate was performed using single crystal X-ray diffraction.
