Benzyl-substituted tin chalcogenides (Bn3Sn)(2)S (1) and (Bn3Sn)(2)Se (2) y
ield polycrystalline-phase pure SnS and SnSe in good ceramic yields when py
rolyzed with S and Se, respectively, at 275 degrees C. Heating mixtures of
(1) and elemental selenium produce solid solutions of the formula Sn(SxSe1-
x). Combustion analysis showed less than 1% residual carbon in all ceramic
products. This methodology allows the complete conversion of tin to tin cha
lcogenides and eliminates the need to synthesize organosulfur and organosel
enium intermediates, (C) 2000 Elsevier Science Ltd.
