Open access
In the 1:1 adduct, C9H7N·C7H7NO2, the carboxyl group is twisted at an angle of 5.42 (8) Å with respect to its attached benzene ring. In the crystal, the carboxylic acid molecule is linked to the quinoline molecule by an O—HN hydrogen bond. The 4-aminobenzoic acid molecules are linked by N—HO hydrogen bonds, forming sheets propagating in (001).

The asymmetric unit of the title compound consists of two independent ion pairs of 4-(dimethylamino)pyridin-1-ium quinolin-8-ol-5-sulfonate (HDMAP+·HqSA−) and neutral N,N-dimethylpyridin-4-amine (DMAP), forming a 1:1:1 cation:anion:neutral molecule co-crystal. The compound has a layered structure, including cation layers of HDMAP+ with DMAP and anion layers of HqSA− in the crystal. The cation and anion layers are linked by intermolecular C—HO hydrogen bonds and C—Hπ interactions.

The crystal structure of the bis(quinoline) adduct dihydrate of tris(tryptaminium 3,5-dinitrobenzoate) shows an extensively hydrogen-bonded and π–π-bonded one-dimensional columnar extension.
organic compounds
In the crystal structure of the title adduct, C7H4N2O6·C9H7N, the 3,5-dinitrobenzoic acid and quinoline molecules are linked into a chain along the b axis by intermolecular O—HN and C—HO hydrogen bonds. Adjacent chains are linked via C—HO hydrogen bonds into layers parallel to the ab plane. A three-dimensional network is formed via π–π interactions.

The crystal structure of di-tert-butylhydroxidoiodidotin(IV), [Sn(C4H9)2I(OH)] or tBu2Sn(OH)I, consists of centrosymmetric dimers exhibiting the characteristic structural features of diorganotin(IV)-hydroxide-halides.
metal-organic compounds
The reaction of AlMe3 with 5,6-benzo[f]quinoline gave the Lewis acid-base adduct Me3Al-BQ, (BQ = benzo[f]quinoline) {(benzo[f]quinoline-N)trimethylaluminium, [Al(CH3)3(C13H9N)]}, with an Al-N bond length of 2.057 (2) Å. This adduct is much less air and water sensitive than the trialkyl metal. The complex was found to be a discrete 1:1 molecular adduct of trimethylaluminium bonded to BQ. The compound contains a tetracoordinate Al atom with distorted tetrahedral geometry.
