Abstract

Diethyltin(IV) complexes formed with carbohydrate ligands (aldoses, polyalcohols, sugar acids and disaccharides) containing the diethyltin(IV) moiety and the carbohydrate ligand in a 1:1 ratio were prepared. Their local structures were determined by extended X-ray absorption fine structure (EXAFS) in the solid state. The results showed that the dioxastannolane units are associated into an infinite chain polymer, in which tin(IV) is bound by two carbon atoms and three or four oxygen atoms either in highly distorted octahedral and trigonal bipyramidal arrangements or in a purely trigonal bipyramidal arrangement. The present structure models are consistent with the results of previous Mössbauer studies, proving the advantages of the use of the partial quadrupole splitting concept for the determination of the symmetry of the coordination sphere in tin(IV) organic complexes.
