Synthesis and crystal structure of 2-(1,3-dithietan-2-yl­idene)cyclo­hexane-1,3-dione

The title compound, C(8)H(8)O(2)S(2), contains a cyclo­hexane-1,3-dione ring, which has a twist-boat conformation. The C(2)S(2) ring is close to planar (r.m.s. deviation = 0.023 Å) and the dihedral angle between the mean planes of the cyclo­hexane and 1,3-dithietane rings is 9.1 (3)°. Short intra­mo...

Sumario:The title compound, C(8)H(8)O(2)S(2), contains a cyclo­hexane-1,3-dione ring, which has a twist-boat conformation. The C(2)S(2) ring is close to planar (r.m.s. deviation = 0.023 Å) and the dihedral angle between the mean planes of the cyclo­hexane and 1,3-dithietane rings is 9.1 (3)°. Short intra­molecular S⋯O contacts occur [2.719 (5) and 2.740 (5) Å]. In the crystal, the mol­ecules are linked by weak C—H⋯S hydrogen bonds and short [3.165 (5) Å] S⋯O contacts, forming (010) layers. The prevalence of these inter­actions is illustrated by an analysis of the three-dimensional Hirshfeld surface and by two-dimensional fingerprint plots.
