title: Carbonates, thiocarbonates, and the corresponding monoalkyl derivatives. 2. X-ray crystal structure of potassium methyltrithiocarbonate (KS(2)CSCH(3)).
abstract: This study presents the first crystal structure determination of a potassium S-alkylthiocarbonate, the title compound potassium methyltrithiocarbonate (KS(2)CSCH(3)) Single crystals of KS(2)CSCH(3) were obtained by the slow introduction of methylene chloride into a saturated solution of KS(2)CSCH(3) in a 1:1 mixture of methylene chloride and tetrahydrofuran at 0 degrees C in a dry N(2) atmosphere. The compound crystallizes in the monoclinic space group P2(1)/c containing Z = 4 K(+) cations and S(2)CSCH(3-) anions per unit cell. The unit cell dimensions are a = 7.6639(3) A, b = 6.5804(2) A, c = 12.8426(5) A, and beta = 91.565(2) degrees. The isomorphism to the structurally closely related compounds KO(2)COCH(3), KOSCOCH(3), and KS(2)COCH(3) is examined.
