✦ Synopsis

Mn II binuclear complexes of Schiff base ligands have been synthesised by the reaction of MnCl P 2H O in ethanolic 2 2

solution with the Schiff base obtained by the condensation of pyridine-2-carboxaldehyde and longer aromatic diamines like 44 X diamino diphenyl, 44 X diamino diphenyl methane and 44 X diamino diphenyl ether respectively. These complexes have been characterised by elemental analysis, spectral, magnetic, electrochemical and FAB mass spectral studies. These complexes have been used as catalyst for the epoxidation of olefin using iodosyl benzene as oxidant. The combined effect of light and catalyst on the catalytic activity have also been investigated.
