Synthesis of d transition metal sulfides from amorphous dithiooxamide complexes

Abstract

Sulfides of six transition or post-transition metals have been prepared by decomposition of amorphous dithiooxamide complexes. The best procedure of pyrolysis corresponds to a heating at 680°C under a dynamic vacuum during 4 hr. This preparation, without any added sulfurizing atmosphere, leads to carbon-free sulfides. © 1994 Academic Press, Inc.
