Carbon Sulphidotelluride, CSTe






Carbon Sulphidotelluride, CSTe, was prepared by Stock and Praetorius in the same way as the previous compound, the anode consisting of 10 or more parts of graphite to 100 of tellurium. Owing to the instability of this substance, its preparation was carried out in a weak light, and below -30° C.; it formed yellowish-red crystals melting at -54° C. to a brilliant red liquid with a garlic-like odour whose density at -50° C. was 2.9. Molecular weight determinations with benzene and carbon disulphide as solvents gave values between 176 and 181, theory for CSTe requiring 172. When kept for a short time at atmospheric temperature carbon sulphidotelluride decomposed completely. The supposed carbon telluride, CTe2, previously described could not be obtained; the phenomena recorded were due to the decomposition of the sulphidotelluride.
