Nuclear monopole and quadrupole hyperfine interaction in organotinhalide and organotinperfluoro compounds

Abstract

Mossbauer effect hyperfine interaction results indicate that the s-electron density at the tin nucleus is less in (C6F5)4Sn than it is in (C6H5)4Sn or (CH3)4Sn. In compounds of the type RnSnX4–n, where R is (CH3), (C6H5), and p-tolyl and X is Cl, Br and C6F5, the largest magnitude of quadrupole splitting and isomer shift is for n= 2. This behaviour could be interpreted as being due to polarization effects via the pπ–pπ and pπ–dπ bonding and the influence of microcrystalline structural effects.
