Synthesis and Characterisation of Some Antimicrobial O-Alkyl/Aryl Trithiophosphate Derivatives of Tin

S. Gaur and K. Joshi

A series of novel complexes have been synthesized with an objective for evaluation of antimicrobial property. Reaction of diorganotin (IV) dichloride with potassium salts of alkyl/aryl trithiophosphate in 1 : 1 and 2 : 1 molar ratio respectively was studied, which gave products of type [ROPS3K2] where R = Me, Et, Pri, Bui and Ph, by solvent free microwave assisted procedure. These derivatives have been characterized by elemental analysis, molecular weight determination and spectroscopic (IR, 1H and 31P NMR) studies. Interestingly, these new synthesized derivatives showed good activity against some bacteria and some fungal strains.
