2-Ethyl-6,6-ethyl­enedisulfanediyl-7-methoxy­methyl-1,2,3,4,5,6-hexa­hydro-1,5-methano­azocino[4,3-b]indol-3-one

The title compound, C(20)H(24)N(2)O(2)S(2), consists of a tetra­cyclic ring system containing an azocino skeleton with ethyl, dithiol­ane and methoxy­methyl groups as substituents. The benzene and five-membered rings are nearly coplanar, with a dihedral angle of 2.78 (11)°. The dithiol­ane ring adopts an envelope conformation. In the crystal structure, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into chains nearly parallel to the c axis. Two C—H⋯π inter­actions are also present.
