MOLECULAR DYNAMICS OF DIORGANOTIN(IV) MERCAPTOCARBOXYLATES FROM VARIABLE TEMPERATURE 119Sn MOESSBAUER SPECTROSCOPY

The molecular dynamics of the diorganotin(IV) 3-mercaptopropionate complexes R2Sn (R = Me, Et, n-Bu, n-Oct, Ph), as well as of the mercaptoacetates R2Sn(SCH2COO), the mercaptosuccinates R2Sn and the mercaptosalicylates R2Sn (R = Me, Ph), have been investigated by variable-temperature 119Sn Moessbauer spectroscopy.The complexes behave as Debye solids with the exception of n-Bu2Sn(IV) and Ph2Sn(IV) mercaptopropionates; the former compound seems to occur in two different solid-state modifications, as characterized by the respective absolute recoil-free fractions.Mean-square displacements of the Moessbauer nuclei suggest the general occurrence of monodimensional polynuclear systems.Application of the effective vibrating mass model evidences two strictly congeneric series consisting of the Alk2Sn(IV) and Ph2Sn(IV) complexes, respectively.On fingerprint criteria, monodimensional polynuclear structures are assumed, which turn to oligonuclear ones for the 3-mercaptopropionates of n-Bu2Sn(IV) and Ph2Sn(IV).
