2-(10',10'-Dimethyl-3'-sulfanyl­idene-4'-aza­tri­cyclo­[5.2.1.0^1,5]decan-2'­-yl)-10,10-dimethyl-4-aza­tri­cyclo­[5.2.1.0^1,5]decane-3-thione

The title compound, C₂₈H₄₀N₂O₂S₂, was obtained as a minor product from an anti-aldol reaction between the corresponding N-propionyl­thiol­actam and benzaldehyde. The asymmetric unit contains one half-molecule, which is completed by inversion symmetry. The molecule displays a nearly eclipsed conformation along the central C-C bond with a C-C-C-C- torsion angle of 20.4 (3)°.
