Abstract

Four di-n-butyltin(IV) complexes have been prepared with sulfanylacetic, 2-sulfanylpropionic, sulfanylsuccinic and m-2,3-disulfanylsuccinic acid, using two different procedures. The compounds were characterised by elemental analysis, Fourier-transform IR, Raman, 119Sn Mössbauer, 1H, 13C and 119Sn NMR spectroscopy. The IR and Raman data indicate the presence of bidentate carboxylate groups, non linear C-Sn-C bonds, and Sn-S bonds. The results of Mössbauer spectroscopic measurements, based on point-charge model calculations, have shown the general occurrence of trigonal-bipyramidal environments at tin(IV). The multinuclear NMR studies also suggested the {O,S} co-ordination of di-n-butyltin(IV) fragment, within the cyclic oligomeric complexes.
