Abstract

A series of 20 complexes of general formula R3SnL (R = CH3, n-C3H7, n-C4H9, C6H5, c-C6H11 ; L = anion of thiophene 2-, thiophene 2-acetic, furoic 2- and pyrrole 2- carboxylic acids) has been prepared. All of these complexes are monomers except those of triphenyltin(IV) which are polymers and have been characterised by molecular weight determination, IR, 1H-NMR and 119mSn Mössbauer studies. Tetrahedral and trigonal bipyramidal structures have been assigned and it has been found that none of the ring hetero atoms bond to tin(IV).
