2-Ethyl-6,6-ethyl-enedisulfanediyl-7-methoxy-methyl-1,2,3,4,5,6-hexa-hydro-1,5-methano-azocino[4,3-b]indol-3-one.

The title compound, C(20)H(24)N(2)O(2)S(2), consists of a tetra-cyclic ring system containing an azocino skeleton with ethyl, dithiol-ane and methoxy-methyl groups as substituents. The benzene and five-membered rings are nearly coplanar, with a dihedral angle of 2.78 (11)°. The dithiol-ane ring adopts an envelope conformation. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains nearly parallel to the c axis. Two C-H⋯π inter-actions are also present.
