Nuclear monopole and quadrupole hyperfine interaction in organotinhalide and organotinperfluoro compounds

Abstract

Mössbauer 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 R_nSnX_4–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 p_π–p_π and p_π–d_π bonding and the influence of microcrystalline structural effects.
