✦ Synopsis

Several di-n-butyltin and diethyltin biscarboxylates and distannoxanes of a-methoxyand a-acetoxy-phenylacetic acids were synthesized and (two of) their structures were studied by means of X-ray diffraction analysis as well as by means of IR and Mossbauer spectroscopies. It was shown for ([(~-BU)~-SnOC(O)CH(OMe)Ph],O}, that there is an interaction between the OMe group and one of the endocyclic tin atoms, resulting in a distorted pentagonal-bipyramidal geometry with the pentagonal plane defined by five 0 atoms and an uncommon seven coordination number for this tin atom. Spectral data indicate that biscarboxylates have truns-octahedral structures.
