TRICYCLOHEXYLTIN(IV) COMPLEXES WITH PICOLINIC, NICOTINIC AND 5-BROMONICOTINIC ACIDS

Abstract

A series of complexes derived from the reactions of tricyclohexyltin(IV) chloride, (C₆H₁₁)SnCl with various carboxylic acids have been synthesized and characterized respectively by using microanalytical, IR, ¹ H, ¹³C and ¹¹⁹Sn NMR spectroscopic methods. (C₆H₁₁)3SnCl reacts with picolinic, nicotinic and 5-bromonicotinic acids leading to the formation of complexes with general formula (C₆H₁₁)₃Sn(H₂O) · L and (C₆H₁₁) ₃SnCl · L (where L = deprotonated carboxylic acid) wherein the carboxylic acid coordinates to the Sn atom via one of the O atoms from the COOH group.
