Acta Crystallogr Sect E Struct Rep Online

Published: May 2009

In the title compound {systematic name: (S)-3-[(aminocar-bonyl)diphenylmethyl]-1-[2-(2,3-di-hy-dro-benzofuran-5-yl)ethyl]pyrrolidinium bromide}, C(28)H(31)N(2)O(2) (+)·Br(-), the pyrrolidine rings adopts an envelope conformation. The two phenyl rings make a dihedral angle of 72.5 (1)°. The four coplanar atoms of the pyrrolidine ring makes dihedral angles of 33.1 (2) and 82.8 (2)° with the two phenyl rings. The mol-ecular conformation is influenced by a C-H⋯O inter-action. In the crystal packing, there are two N-H⋯Br hydrogen bonds running in opposite directions. They appear to form C(10) and C(9) chain motifs in the unit cell. In addition, the mol-ecular packing is further stabilized by C-H⋯Br and C-H⋯O hydrogen bonds. The C atom bonded to the benzofuran ring system is disordered in a 0.66:0.34 ratio.

Two new phenyl-sulfonyl-indole derivatives, namely, -{[3-bromo-1-(phenyl-sulfon-yl)-1-indol-2-yl]meth-yl}--(4-bromo-3-meth-oxy-phen-yl)benzene-sulfonamide, CHBrNOS, (), and ,-bis-{[3-bromo-1-(phenyl-sulfon-yl)-1-indol-2-yl]meth-yl}benzene-sulfonamide, CHBrNOS, (), reveal the impact of intra-molecular π-π inter-actions of the indole moieties as a factor not only governing the conformation of ,-bis-(1-indol-2-yl)meth-yl)amines, but also significantly influencing the crystal patterns. For , the crystal packing is dominated by C-H⋯π and π-π bonding, with a particular significance of mutual indole-indole inter-actions. In the case of , the mol-ecules adopt short intra-molecular π-π inter-actions between two nearly parallel indole ring systems [with the centroids of their pyrrole rings separated by 3.

Crystal growth of 2-(3,4,5-triphen-ylphen-yl)acetic acid () from aceto-nitrile yields a monosolvate, CHO·CHCN, of the space group 1. In the crystal, the title mol-ecule adopts a conformation in which the three phenyl rings are arranged in a paddlewheel-like fashion around the central arene ring and the carboxyl residue is oriented nearly perpendicular to the plane of this benzene ring. Inversion-symmetric dimers of O-H⋯O-bonded mol-ecules of represent the basic supra-molecular entities of the crystal structure.
