Studies on Some Mixed Schiff’s Base Complexes. V.

Abstract As regards the preparation and characterization of some new mixed complexes of the type MLL′ where M=Cu(II), Ni(II); L=salicylaldimine and L′=(o-hydroxybenzyl)(ethylideneamine) or o-hydroxydiphenylenethylene-amine or their derivatives, we have carried out the preparation of a few similar types of complexes where L′=2-hydroxy-1-naphthylmethyleneamine. The mixed imine Schiff’s base complexes have been prepared by treating the metal ammine complex with an equivalent amount of salicylaldehyde and 2-hydroxy-1-naphthaldehyde. Amine exchange reactions were also been carried out by treatment of mixed imine Schiff’s base complex with ethylenediamine(en) or propylenediamine(pn). The complexes of new Schiff’s base were formed where diamine have salicylaldehyde condensed at one end and 2-hydroxy-1-naphthaldehyde at the other end. The complexes have been characterized by elemental analysis, TLC analysis, conductance measurements, magnetic measurements, and spectral analysis.
