The syntheses of bis(2-cyanoethyl)tin dibromide and (cyanoethyl)-tin tribromide by reaction of bromine with diphenylbis(2-cyanoethyl)tin and triphenyl(2-cyanoethyl)tin, respectively, in an inert solvent are reported. Based on the nitrile absorption bands in nujol, it is concluded that tris(2-cyanoethyl)tin bromide and (2-cyanoethyl)tin tibromide, but not bis(2-cyanoethyl)tin dibromide, are associated in the solid state. The nature of these associations are discussed in detail. Molecular weight determinations show that tris(2-cyanoethyl)tin bromide and bis(2-cyanoethyl)tin dibromide are monomeric in tetrahydrofuran and that (2-cyanoethyl)tin tribromide is monomeric in benzene.
