A mössbauer study of some tin complexes with sulfoxides

Mössbauer spectrsocopy has been used to study six 1:1 triphenyltin chloride, four 1:2 dimethyltin dichloride and one 1:1 trimethyltin chloride sulfoxide complexes.

An increase in quadrupole splitting on complexation was found for all complexes, although it remains practically constant for each acceptor molecule. While the isomer shifts of the triphenyltin complexes are constant and, furthermore, are approximately the same as that for neat triphenyltin chloride, a significant decrease was observed on complexation of dimethyltin dichloride and trimethyltin chloride.

From the temperature dependence of the area under the Mössbauer lines it was possible to estimate the Debye temperatures for the dimethylsulfoxide-triphenyltin chloride and the di-n-propylsulfoxide-dimethyltin dichloride complexes.
