Synthesis and characterizations of tin(IV)trithiophosphates and their adducts with nitrogen donor bases

Bis-(trithiophosphato)tin(IV) [(RO)P(S)S-2](2)Sn (where R = n-C3H7,i-C3H7,i-C3H7, i-C5H11,-C6H5) were prepared by a reaction of methanolic solution of SnCl4 and dipotassium salt of trithiophosphates in a 1:2 molar ratio, and their adducts [(RO)P(S)S-2](2)Sn. N2C12H8 and [(RO)P(S)S-2](2)Sn. N2C10H8 were prepared by a reaction of methanolic solution of [(RO)P(S)S-2](2)Sn and N-donor bases in a 1:1 molar ratio. These newly synthesized derivatives have been characterized by elemental analysis; molecular weight measurement; and IR, C-13, P-31, and Sn-119 NMR spectral studies. A coordination number of four and six is suggested for trithiophosphates of tin(IV) and their adducts with N-donor bases, respectively.
