Resumen:
The lattice-dynamical properties of the intermediate oxide of tin (IO) have been investigatedover the temperature range 80-295 K. The logarithm of the recoil-free fraction variedlinearly with temperature. However, a Debye model does not give a good account of this dependence.By comparison with the other oxides of the Sn-O system, the recoil-free fraction for tinatoms with 2+ and 4+ oxidation states of the IO were estimated. At room temperature, theyare 0.46 and 0.32 for 4+ and 2+ states respectively.
