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—H...N hydrogen bond. The 4-amino­benzoic acid mol­ecules are linked by N—H...O 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—H...O hydrogen bonds and C—H...π inter­actions.

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—H...N and C—H...O hydrogen bonds. Adjacent chains are linked via C—H...O 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.

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.
