Abstract
The Mössbauer resonance spectra of the compounds isolated in the SnF 2SnF 4 system have been studied. The isomer shifts allowed the authors to locate the tin atoms in different chemical environments. The results have been correlated with the electronic structures of both oxidation states of tin and an estimate of the ionicities of the bonding orbitals has been given. For tin(IV) the quadrupole splitting can be explained by means of unequivalent neighboring fluorine atoms. For tin(II) it can be interpreted in terms of p-character and hybrid nature of bonding and non-bonding orbitals. A Goldanskii-Karyagin effect is observed for αSnF 2, Sn 3F 8 and Sn 7F 16.
