Chemical applications of the Mössbauer effect. Part IV. Compounds containing tin–metal bonds

Abstract

Mössbauer spectra have been obtained for a series of organotin compounds in which the tin atom is covalently bonded to another tin or other metal atom. Compounds studied include Ph₄Sn, (Ph₃Sn)₂, (Ph₃Sn)₂SnPh₂, (Ph₃Sn)₄Sn, (Ph₃Sn)₄Ge, and (Ph₃Sn)₄Pb. Despite the absence of a regular tetrahedral environment for the tin atom in most of these compounds, no observable quadrupole effect was detected. This unexpected result is discussed in terms of structures and bonding.
