title: 4-Fluoro-N-methyl-N-(1,2,3,4-tetra-hydro-carbazol-3-yl)benzene-sulfonamide.
abstract: In the title compound, C(19)H(19)FN(2)O(2)S, the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the plane of the fluoro-phenyl ring forms a dihedral angle of 41.5 (1)° with respect to the carbazole mean plane. The crystal structure is segregated into layers containing the carbazole units and fluoro-phenyl rings in alternate (200) planes. The carbazole units form centrosymmetric face-to-face inter-actions [inter-planar separation = 4.06 (1) Å] and edge-to-face inter-actions in which the N-H group is directed towards an adjacent carbazole face, with a shortest H⋯C contact of 2.53 Å. The fluoro-phenyl rings form face-to-face contacts with an approximate inter-planar separation of 3.75 Å and a centroid-centroid distance of 4.73 (1) Å.
