The complete mol-ecule of the title compound, C(19)H(34)N(2)S, is generated by crystallographic twofold symmetry, with the C=S group lying on the rotation axis. A short C-H⋯S contact occurs in the mol-ecule. The five-membered ring is twisted and the cyclo-hexyl ring adopts a chair conformation. The dihedral angle between the mean plane of the five-membered ring and the basal plane of the cyclo-hexyl ring is 75.32 (13)°.
