Infrared spectra support a covalent monomeric tin(IV) structure for the chlorides (2). Hydrogen-1, and in some cases 13C, n.m.r. spectra for (2) or (3) in benzene or methylene chloride solutions are consistent with a monomeric Cs molecular structure, showing diastereotopically distinct SiMe3 groups. Addition of (CD3)2SO or C5D5N leads to collapse of these doublets or, for R = But, a decrease in their
