Sulfide Telluride

The thermally very unstable carbon sulfide telluride is a yellow-reddish solid that melts at — 54° to a red liquid. The red liquid rapidely decomposes (even in the absence of air) at 20° to a black, non-volatile substance. Solutions were observed to decompose similarly. Carbon disulfide was identified as one of the decomposition products. Light accelerated the decomposition of dissolved carbon sulfide telluride.  

Carbon sulfide telluride was prepared by allowing a direct-current arc to burn between a graphite and a graphite/tellurium electrode. The electrodes were immersed into carbon disulfide kept at

Without going into details, we may assume that the energy of such bonds is related to the reduction in the free energy observed in the formation of double or more complex salts, oxides, sulfides, tellurides, etc., which has been observed in many substances. The thermodynamic data (AS, AZ) indicate that this tsqje of bond in double salts becomes weaker with increasing temperature, and this provides an opportunity for electron exchange between increasing numbers of ions having different valences.
