tetraphosphorus heptasulfide
Molecular formula :
MW :
CAS :

nature : P4S7 yellow crystal. The air humidity is very sensitive, explained released H2S Yi River. There are two crystal. Below 242 ° C for the monoclinic of α-density 2.19; Above 242 ° C for the β - orthogonal. The temperature of 308 ° C. Α-the molecular structure of the map available in two forms said. From red phosphorus and chemical measurement of sulfur, in an inert atmosphere, heated to 300 ° C over direct synthesis. Α - P4S7 crystallization can P4 from sunlight and the CS2 S8 solution to I2 catalyst in the system.
