Tin-119 Mössbauer spectra of trichlorotin complexes
Abstract
The range of available 119Sn Mössbauer data for the trichlorotin system has been extended. Variations of the Mössbauer parameters are rationalised by considering the effect of the donor ability of the ligand L in the complex LSnCl3. This approach is shown to be consistent with available i.r. and crystallographic data. The data strongly suggest that the Mössbauer centre shift does not provide a good distinction between formal SnII and SnIV species in many cases and that a valence-bond (hybridisation) approach is more meaningful.
