Spectral and antimicrobial studies of organotin(IV) complexes of bidentate Schiff bases having nitrogen and sulphur donor system

Abstract

The complexes of composition R2Sn(L)2 and RjSnL (where R = butyl and L = monoanion of Schiff bases of S-benzyldithiocarbazate) have been prepared by the reaction of Schiff bases with metal oxides. The newly synthesized complexes have been characterized by elemental analysis, conductance measurements and molecular weight determinations. The mode of bonding and geometry of the complexes have been suggested on the basis of IR, UV and multinuclear 'H, i3C and Sn NMR spectral studies. Schiff bases and their tin complexes have also been screened for their antibacterial activities, as several bacteria are quite active in this respect
