Complex anionic metal sulfides and process for their preparation

Abstract

Transition metal complex sulfides contg. the NH2R2+ group are prepd. by treating with H2S an anhyd. org. soln. of a carbamate Mz(O2CNR2)z, where M is a transition metal and R is an alkyl group. Semiconductors are prepd. (NH2Et2)2Co6S7, (NH2Et2)2Ni8S9, (NH2iso-Pr2)10Fe16S29, (NH2Et2)6Fe8S15, (NH2Et2)2Cu14S15, and (NH2 iso-Pr2)2Cu14S15 were prepd
