The title compound, C(18)H(12)N(2)O, crystallizes in a zwitterionic form. The dihedral angle between the planes of the benzene ring and naphthalene ring system is 13.95 (5)°. An intra-molecular N-H⋯O inter-action results in the formation of a planar six-membered ring, which is oriented at dihedral angles of 13.50 (4) and 4.49 (4)° with respect to the benzene ring and naphthalene ring system, respectively. In the crystal structure, inter-molecular C-H⋯O and C-H⋯N inter-actions link the mol-ecules into a two-dimensional network. π-π contacts between the naphthalene systems [centroid-centroid distance = 3.974 (1) Å] may further stabilize the structure.

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.

The asymmetric unit of the title compound, [Co(CBrO)(CHN)(HO)] or [Co(Brbdc)(im)(HO)] , comprises half of Co ion, tetra-bromo-benzene-dicarboxylate (Brbdc), imidazole (im) and a water mol-ecule. The Co ion exhibits a six-coordinated octa-hedral geometry with two oxygen atoms of the Brbdc ligand, two oxygen atoms of the water mol-ecules, and two nitro-gen atoms of the im ligands. The carboxyl-ate group is nearly perpendicular to the benzene ring and shows monodentate coordination to the Co ion.
