Several di‐n‐butyltin and diethyltin biscarboxylates and distannoxanes of α‐methoxy‐ and α‐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 Mössbauer spectroscopies. It was shown for {[(n‐Bu) 2 ‐SnOC(O)CH(OMe)Ph] 2 O} 2 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 O atoms and an uncommon seven coordination number for this tin atom. Spectral data indicate that biscarboxylates have trans ‐octahedral structures.
