2-Ethyl-6,6-ethyl-enedisulfanediyl-7-methoxymethyl-1,2,3,4,5, 6-hexa-hydro-1,5-methanoazocino[4,3-b]indol-3-one

The title compound, C₂₀H₂₄N₂O ₂S₂, 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 molecules into chains nearly parallel to the c axis. Two C - H⋯π interactions are also present.
