The low frequency Raman Spectra (0 - 350 cm-1) of [(CH3)2 NH2]2 Sn Cl6 (2MHS) and [(CH3)3 NH]2 Sn Cl6 (3MHS) were recorded on single crystals at room temperature. The Spectra have been assigned on the basis of group theory analysis of vibrations and in view of the previously reported structural data of these two hexachlorostannate compouds. Their corresponding structures are derived from the Fm3m antifluorite structure.
