title: Dialkyltin(IV)bis(O-tolyl/benzyldithiocarbonate) complexes: spectroscopic, thermogravemetric, antifungal and crystal analysis of n-Bu2Sn(S2COCH2C6H5)2.
abstract: Novel compounds of dimethyl- and dibutyltin(IV) with O-tolyl/benzyldithiocarbonates were successfully obtained by the reaction of Me(2)SnC(l2) and n-Bu(2)SnCl(2) with sodium salt of O-tolyl/benzyldithiocarbonates, [o-, m- and p-CH(3)C(6)H(4)OCS(2)Na and C(6)H(5)CH(2)OCS(2)Na], in 1:2 molar ratio in dry toluene. The structure of these newly synthesized complexes has been examined by elemental analysis, FT-IR, multinuclear NMR ((1)H, (13)C and (119)Sn) spectroscopy. The thermal behaviour of the complex (8) has been studied by TGA/DTA analysis. The complex (8), n-Bu2Sn(S2COCH2C6H5)2, crystallizes in the monoclinic space group C2/c, in which tin adopts a distorted octahedron or skew trapezoidal bipyramidal geometry accompanied by two n-butyl chains and the two dithiocarbonate ligands coordinated in an anisobidentate fashion. Antifungal activities against fungus Fusarium sp. of these organotin(IV) derivatives exhibited enhanced activity compared to the free ligands.
