Abstract
Three nickel(II) complexes of general formula NiL2, where L is a unsymmetri cal N2O ligand prepared by Schiff condensation of propane-1,3-diamine with salicylaldehyde (Hslp), 3-methoxysalicylaldehyde (Hmslp) or 2-hydroxyl-l-na phthaldehyde (Hnlp) have been prepared. Characterisation of nickel complexe s by spectroscopic methods indicates that they are six-coordinate with the amine group bound to the nickel centre. The accessibility of the + 3 and I oxidation states for the complexes was evaluated by coupling electrochemi cal techniques and EPR spectroscopy.
