    1-tert-Butyl 2-ethyl 5-bromo-3-(thiophen-2-ylcarbonyl)-1H-indole-1,2-dicarboxylate
    (International Union of Crystallography, 2013-01-16) Hassam, Mohammad; Smith, Vincent J.
    ENGLISH ABSTRACT: In the title compound, C21H20BrNO5S, the thiophene group is located above the mean plane of the indole ring and displays rotational disorder (i.e. rotation through 180). The site occupancy of the major component is 0.902 (2), while that of the minor component is 0.098 (2). In the crystal, pairs of weak C—HO interactions link the molecules into centrosymmetric dimers.

    5-Chloro-1-(4-methyl­phenyl­sulfon­yl)-1H-indole
    (International Union of Crystallography, 2012-10) Hassam, Mohammad; Smith, Vincent J.
    In the title compound, C15H12ClNO2S, the indole ring is essentially planar (r.m.s. deviation = 0.0107 A˚ ) and makes a dihedral angle of 85.01 (6) with the benzene ring. In the crystal, three C—HO hydrogen bonds result in a hydrogenbonded spiral running parallel to the c axis.
