摘要

The title compound, (C6H11)3PS (systematic name: tri­cyclo­hexyl-λ5-phosphane­thione), is a triclinic (P-1, Z′ = 1) polymorph of the previously reported ortho­rhom­bic form (Pnma, Z′ = 1/2) [Kerr et al. (1977). Can. J. Chem. 55, 3081–3085; Reibenspies et al. (1996). Z. Kristallogr. 211, 400]. While conformational differences exist between the non-symmetric mol­ecule in the triclinic polymorph, cf. the mirror-symmetric mol­ecule in the ortho­rhom­bic form, these differences are not chemically significant. The major feature of the mol­ecular packing in the triclinic polymorph is the formation of linear chains along the a axis sustained by methine-C—H⋯S(thione) inter­actions. The chains pack with no directional inter­actions between them. The analysis of the Hirshfeld surface for both polymorphs indicates a high degree of similarity, being dominated by H⋯H (ca 90%) and S⋯H/H⋯S contacts.
