Abstract Temperature dependent119Sn Mössbauer effect measurements on AuSn4, PdSn4, and PtSn4 compounds in the temperature range of 10 to 295 K shows the presence of a Sn4+ site. Variation of thermal shift and the Debye-Waller factor shows that the mean-squared displacement (lnf) and mean-squared velocity (δ) of the tin nuclei are both characterized by a Debye temperature of 238, 255, and 304 K in AuSn4, PdSn4, and PtSn4, respectively. No discernible evidence of a phonon mediated structural transition is observed in the temperature range studied.
