Intermolecular Dynamics of Organotin Compounds from Mossbauer and Raman Spectroscopy

The correlation between chemical structure and the lattice dynamical behavior of the constituent atoms of a solid is of primary importance since those are two complementary aspects of bonding in solids. However, relatively little data in this area are available from classical experimental techniques. Ellipsoids of vibration deduced from the thermal scattering factors in x-ray diffraction studies have provided the bulk of the information available on the anisotropy of atomic motion in single crystalline materials. In recent years, Mossbauer effect spectroscopy — in particular the temperature dependence of the recoil-free fraction and the Gol’danskii-Karyagin asymmetry — has made available additional precision data on the details of the dynamical behavior of atoms in a condensed matrix.1,2 One of the limitations of this technique is that the effective lattice temperature and the mass of the vibrating entity in the lattice are reflected in the single experimental quantities (e.g.: the temperature dependence of the recoil-free fraction or the second order Doppler shift) deduced from the data and can, in general, not be independently determined from Mossbauer measurements alone.

    A. G. Davies, H. J. Milledge, D. C. Puxley and P. J. Smith, J. Chem. Soc. A, 2862 (1970) drew this inference from the departure from Td symmetry of (CH3)2SnCl2. Despite the erroneous statement in Ref. 8, this association has not “been inferred from 119Sn Mossbauer data. In fact, the contribution of crystal stacking forces to the molecular symmetry in (C6H5)2SnCl2 is discussed in detail in Ref. 9, and no speculation concerning intermolecular bonding seen warranted by the available data.Google Scholar
