Summary

Six new hydrazones chelating agents (1–6) have been prepared and characterized by physical and spectral methods. Only two of these ligands (1 = HL1) and (2 = HL2) yield stable complexes with divalent metals NiII and CuII. Hydrazones (1) and (2) behave as monobasic bidentate ligands towards the metal cations. The spectroscopic evaluation and elemental analyses are all in agreement with structural formulae M(L1)2 and M(L2)2.
