Reactivity of triphenyltin(IV) O,O'-dialkyl/alkylene dithiophosphates with Lewis bases

394-397The interactions of triphenyltin(IV) O,O'-dialkyl/alkylene dithiophosphates, [(C6H5)3SnS(S)P(OR)2] and [(C6H5)3SnS(S) IPOGOI] [R= -CH(CH3)2, -CH2CH2OCH3 ; G= -CH2C(CH3)2CH2-, -CH2C(CH3)2CHCH (CH3)2] with various S-,O- and N- donor Lewis bases yield several new molecular adducts. On the basis of elemental analysis and spectral (IR, 1H and 31P NMR) data, the presence of five- and six-coordination of Sn atom in case of unidentate and bidentate Lewis bases, respectively is concluded
