Potassium trithiocarbonate
Chemical compound / From Wikipedia, the free encyclopedia
Potassium trithiocarbonate is the inorganic compound with the chemical formula K2CS3. It is the potassium salt of trithiocarbonic acid. It consists of two potassium cations K+ and the trigonal planar trithiocarbonate dianion CS2−3. It is a white solid, although impure samples often appear brown. It is prepared by the reaction of potassium sulfide or potassium hydrosulfide with carbon disulfide.
- K2S + CS2 → K2CS3
