RESUMO

Some mixed sulfur donor ligand complexes of antimony(III) of the general formula [(R(2)NCS(2))](2)SbS(2)COR' where R = CH(3), C(2)H(5) and R' = Me, Et, Pr(n), Pr(i), Bu(n) and Bu(i) have been synthesized by the reaction of antimony(III) bis(dialkyldithiocarbamate) chloride with potassium organodithiocarbonate in an equimolar ratio by stirring at room temperature in benzene/CS(2) mixture. These complexes have been characterized by physicochemical [elemental analysis, melting points and molecular weight determinations] and spectral [UV, IR, Far-IR, NMR ((1)H and (13)C), FAB(+) mass and powder X-ray diffraction] studies. Free ligands and synthesized complexes have also been screened against different bacterial strains and results obtained made it desirable to delineate a comparison between free ligands, standard drug used and synthesized complexes.

RESUMO

Replacement reactions of toluene-3,4-dithiolatoantimony(III) chloride with oxygen and/or sulphur donor ligands like benzoic acid, thiobenzoic acid, thioacetic acid, phenol, thiophenol, sodium salicylate and thio glycolic acid in 1:1 molar ratio as well as disodium oxalate in 2:1 molar ratio in refluxing anhydrous benzene yielded toluene-3,4-dithiolatoantimony(III) mono oxo and/or thio carboxylic or phenolic derivatives of the general formula {R=OOCC(6)H(5), SOCC(6)H(5), SOCCH(3), OC(6)H(5), SC(6)H(5), OOCC(6)H(4)(OH) and SCH(2)COOH} and These newly synthesized derivatives are yellow and brown solids/liquids and are soluble in common organic solvents like benzene, chloroform, dichloromethane, etc. These derivatives have been characterized by melting point determination, molecular weight determination, elemental analysis (C, H, S and Sb), spectral {UV, IR and NMR ((1)H and (13)C)} and thermal (TGA, DTA and DSC) studies.
