SYNTHESIS AND CHARACTERIZATION OF MACROCYCLIC COMPLEXES

P. R. Shirode*

Abstract

A novel series of complexes of the type [M(C32N4H28)X]X2, where M = Cr(III), Fe(III) and Mn(II), X = Cl−, NO3 − and (C32N4H28) corresponds to the tetra dentate macrocyclic ligand, were synthesized in ethanolic media by the template condensation of benzyl and ethylene diamine in the presence of transition metal salts. The complexes were characterized by elemental analyses, conductance and magnetic measurements, and UV/Vis and IR spectroscopy. Based on these studies, a six-coordinate square octahedral geometry for all the prepared complexes is proposed. All the synthesized macrocyclic complexes were tested for their microbial activity against four different microorganisms E.coli., Baciullus Sp Staphylococcus sp., and Proteus Sp. antifungal activity; ethylene diamine; template synthesis; macrocyclic Schiff-base complexes.
