High-resolution 119Sn spectra of solid trimethyltin fluoride (I), tri-isobutyltin fluoride (II), and triphenyltin fluoride (III) show that all the compounds are five-coordinate in the solidstate, with the 119Sn nucleus apparently equally coupled to two fluorines. In contrast, the spectrum of trimesityltin fluoride (IV) indicates, in conformity with X-ray results, that the tin is four-coordinate and
