NMR measurements ( 119 Sn chemical shift, line width and 13  C relaxation) were made on triphenyltin chloride in two solutions, 2.5 and 0.75 mol% in CDCl 3 , at several temperatures. The 13  C spin–lattice relaxation time and NOE data for the phenyl carbons provide the corresponding correlation times for the overall molecular reorientational motion and the internal rotation of the phenyl groups. The results are indicative of a weak intermolecular association of the triphenyltin chloride molecules in solution and are discussed with reference to a model for intermolecular phenyl ring π–π stacking interactions.
