Abstract

The crystal structure of 9-benzenesulfonyl-1-keto-3-thia-1,2,3,4-tetrahydrocarbazole (C17H13NO3S2), has been determined. The compound forms crystals of parallelopiped shape and crystallizes in triclinic space group P1 with cell dimensions a = 7.887(6), b = 9.210(6), c = 11.280(5) angstroms, α = 106.47(5), β = 75.72(6), γ = 101.57(4)°, V = 753.9(8) angstroms3, Z = 2, Dcal = 1.513 Mgm-3 and T = 298 K. The structure was solved by direct methods and refined by full-matrix least-squares to a final R value of 0.066 with 2861 unique reflections. The heterocyclic six-membered ring of the carbazole moiety adopts half-boat conformation. The phenylsulfonyl substituent occupies equatorial position at N and is inclined by an angle of 71.2(5)° to the carbazole moiety. The N atom lies 0.162(3) angstrom out of the plane of the three atoms bonded to it. The S1 atom possesses usual distorted tetrahedral geometry.
