This study presents the first crystal structure determination of a potassium S-alkylthiocarbonate, the title compound potassium methyltrithiocarbonate (KS2CSCH3) Single crystals of KS2CSCH3 were obtained by the slow introduction of methylene chloride into a saturated solution of KS2CSCH3 in a 1:1 mixture of methylene chloride and tetrahydrofuran at 0 °C in a dry N2 atmosphere. The compound crystallizes in the monoclinic space group P21/c containing Z = 4 K+ cations and S2CSCH3- anions per unit cell. The unit cell dimensions are a = 7.6639(3) Å, b = 6.5804(2) Å, c = 12.8426(5) Å, and β = 91.565(2)°. The isomorphism to the structurally closely related compounds KO2COCH3, KOSCOCH3, and KS2COCH3 is examined.
