Synthesis and characterization of O-alkyl, O-cycloalkyl and O-aryl trithiophosphato derivatives of trimethyltin(IV) chloride and tributyltin(IV) chloride

Trimethyltin(IV)trithiophosphates [(RO)P(S)S-2][Sn(Me)(3)](2) and tributyl tin (I-V)trithiophosphates [(RO)P(S)S-2][Sn(Bu)(3)](2) (R=CH3, -C2H5, C3H7, -C3H7iso -C4H9n, -C4H9iso, -C4H5scc, -C5H11iso, C6H5) were prepared in methanolic solution of R3SnCl and dipotassium salt of trithiophosphates in 2:1 molor ratio. These newly synthesised derivatives have been characterized by elemental analysis, molecular weight measurements, IR, C-13, P-31 and Sn-119,NMR spectral studies. Coordination number of four suggested for tin(IV) in these derivatives.
