In the title compound, C(13)H(22)N(4)O(2)S(2), the six-membered ring displays a half-chair conformation. The olefin amine unit is close to being coplanar with the imidazolidine ring (r.m.s. deviation = 0.059 Å). The dithiol-ane ring adopts a twisted conformation. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions.
