Synthesis of Bi_2−2xSb_2xS₃ (0 ≤ <i>x</i> ≤ 1) solid solutions from solventless thermolysis of metal xanthate precursors

Abstract

Tris(<italic>O</italic>-ethylxanthate)bismuth(<sc>iii</sc>) (<bold>1</bold>) and tris(<italic>O</italic>-ethylxanthate)antimony(<sc>iii</sc>) (<bold>2</bold>) were synthesized and used as precursors for the preparation of Bi_2−2xSb_2xS₃ alloys (<italic>x</italic> = 0, 0.2, 0.4, 0.6, 0.8 and 1) using melt reactions.
