Potassium trithiocarbonate is the inorganic compound with the formula K₂CS₃. It consists of two potassium cations and the planar trithiocarbonate dianion. 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. Potassium trithiocarbonate reacts with alkylating agents to give trithiocarbonate esters:^[1]
