Abstract

Heterobimetallic Cu, Zn and Mn complexes {ZnCu(Ln)(CH3OH)3).xCH3OH (H4L1) (1), H4L2 (2);x =0,1), and [MnCu(Ln)(CH3OH)3).xCH3OH ((H4L1(3),H4L2 (4),x =0,1) (H4L1 = disalicy laldchydesucclnoyldihydrazone, H4L2= bis(2-hydroxy-l-naphthal(Jehyde)succinoyldihydrazonc) have beep synthesized using monometallic copper complexes as metallollgand in methanol medium. Complexes have been characterized by means of elemental analysis, molar conductance, UV-VIs, I'R spectroscopy, magnetic moment and ESR. The value for the ZnII-CuII complexes fall In the range 1.73- 1.75 B.M. while for MnII-CuII complexes fall In the region 3.24-3.43 B.M. Electronic spectroscopy suggests that the s copper centre has a pseudo square pyramidal stereochemistry in all the complexes while the second metal centre has a distorted octahedral stereochemistry, The dihydrazones are present in enol form in the complexes. The electron transfer reactions of the complexes have been investigated by cyclic voltammetry. © Scientific Publishers. All rights reserved.
