A PMR study of solvent effects on some p ‐substituted phenyltin chlorides (substituents = CH 3 , (CH 3 ) 3 C, CH 3 O) is reported. Co‐ordination of solvent molecules to the tin atom leads to an unusual low field shift of the o ‐ring protons. The results for p ‐tolytin trichloride have been compared with those for p ‐tolylsilyl trichloride and discussed. In o ‐, m ‐ and p ‐tolyltin trichlorides long range spin‐spin couplings between the ring methyl protons and the tin atom have been observed. The order of magnitude is o ‐ > p ‐ > m ‐methyl protons.
