title: 6-Bromo-2-[(E)-thio-phen-2-yl-methyl-idene]-2,3,4,9-tetra-hydro-1H-carbazol-1-one.
abstract: In the title compound, C(17)H(12)BrNOS, the cyclo-hexene ring deviates only slightly from planarity (r.m.s. deviation for non-H atoms = 0.047 Å). In the crystal, the mol-ecules are linked into centro-symmetric R(2) (2)(10) dimers via pairs of N-H⋯O hydrogen bonds. The thio-phene ring is disordered over two positions rotated by 180° and with a site-occupation factor of 0.843 (4) for the major occupied site.
