S-Benzylthio thioacetate, C9H10OS2, Mr = 198.31, monoclinic, P2(1), a = 5.7112(5), b = 8.1912(5), c = 10.6486(8) A, beta = 92.230(8) degrees, V = 497.8(1) A3, Z = 2, Dm = 1.32(1), Dx = 1.323 Mg m-3, lambda(Mo K alpha) = 0.71073 A, mu = 0.47 mm-1, F(000) = 208, T = 299(1) K, RF = 0.024 for 812 reflections. In this molecule, the S-S [2.024(1) A] and S-C [1.802(3), 1.825(4) A] distances are typical and the C-S-S-C dihedral angle [-80.5(1) degree] lies at the lower end of the range reported for related compounds. The acetyl and disulfide groups are coplanar to within +/- 0.01 A. As a consequence, the molecule exhibits a short [3.078(2) A [intramolecular S...O contact.
