3,3-Ethyl-enedithio-3,3a,4,5,10,10b-hexa-hydro-2H-furo[2,3-a]carbazole
Abstract:
The title compound, C(16)H(17)NOS(2), consists of a carbazole skeleton with tetra-hydro-furan and dithiol-ane rings. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 1.57 (15)°. The cyclo-hexenone and tetra-hydro-furan rings have envelope conformations, while the dithiol-ane ring adopts a twist conformation. In the crystal structure, pairs of weak inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers with R(2) (2)(16) ring motifs. Weak C-H⋯π inter-actions may further stabilize the structure.

Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.
