Potentiometric spectroscopic and X-ray studies of the open chain oxime ligand, N,N′-bis(2-hydroxyimino-propionyl)propane-1,3-diamine and its complexes with NiII and CuII ions showed a very high efficacy of the ligand studied in the co-ordination of both CuII and NiII ions. The metal complexes are very stable and square-planar with four nitrogens involved in metal-ion binding. These complexes may be additionally stabilised by hydrogen bonds between two oxime oxygen atoms.
