The crystal structure of 9‐benzenesulfonyl‐1‐keto‐3‐thia‐1,2,3,4‐tetrahydrocarbazole (C 17 H 13 NO 3 S 2 ), 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) Å, a = 106.47(5), b = 75.72(6), g = 101.57(4), V = 753.9(8) Å 3 , Z = 2, D cal = 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)Å out of the plane of the three atoms bonded to it. The S1 atom possesses usual distorted tetrahedral geometry.
