摘要:
The condensed phase reactions of tribenzylbismuth or tribenzylantimony and elemental sulfur under mild thermal conditions (275 degrees C) produces the respective sesquisulfides in good yields and high purity. A mixture of the perbenzylated metals and elemental sulfur produces solid solutions of the general formula (BixSb1-x)(2)S-3. It has been demonstrated that it is possible to achieve synthetic control over the size and microstructure of the as produced metal sulfide particles by simply changing reaction conditions. In combination with the condensed phase pyrolysis of tris(benzylthiolato)bismuth, five different microstructures for bismuth sulfide are accessible through compounds containing the benzyl ligand.
