organotin cations in the solid state is corroborated by new examples. Treating R3SnN(SO2Me)2 (R = Me, Ph) with two equivalents of L = hexamethylphosphorotriamide (HMPA), Ph3AsO, imidazole (Him) or 4-dimethylaminopyridine affords the complete series of eight ionic complexes [R3Sn(L)2]+[(MeSO2)2N]−. With one equivalent of pyridine-N-oxide (pyO), the triorganotin dimesylamides form the presumably uncharged
