Synthesis and Biological Activity of 2-Methylpiperazine- Dithiocarbamato and Di-(2-Methyl-5-Chlorophenyl) Dithiophophinato Derivatives of Triorganotin (IV) Chloride

摘要

Complexes of triphenyltin(IV) chloride with 2-methyl-piperazinedithiocarbamate (Na salt,2-Mepipzdtc) and di-(2-methyl-5-chlorophenyl) diphosphinate (Na saMeCldtpi) have been synthesised and characterised by elemental analysis, IR and ~1H-NMR studies. Unlike the symmetrical bidentate nature of the dithiocarbamato group an unsymmetrical bidentate ligation is suggested for the dithiophosphinato group towards organotin (IV) moiety. The thermal stability of the compouds, biological activity against E. coli and potential antifungal role of the compounds in wood preservaation have been evaluated.
