چکیده
In the title compound, C(9)H(8)N(2)O(2)S, the sulfamoyl NH(2) group is involved in intra-molecular N-H⋯N and inter-molecular N-H⋯O hydrogen bonding. In the crystal, molecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers, which are further associated through π-π stacking inter-actions between the quinoline benzene rings [centroid-centroid distance = 3.649 (1) Å] into a one-dimensional polymeric structure extending along the a axis.

Microbial transformation of quinoline by a Pseudomonas sp.
A Pseudomonas sp. isolated from sewage by enrichment culture on quinoline metabolized this substrate by a novel pathway involving 8-hydroxycoumarin. During early growth of the organism on quinoline, 2-hydroxyquinoline accumulated as the intermediate; 8-hydroxycoumarin accumulated as the major metabolite on further incubation. 2,8-Dihydroxyquinoline and 2,3-dihydroxyphenylpropionic acid were ide...

Crystals of the title compound, 2C(26)H(18)N(4)O(2)·C(7)H(8), were obtained from the reaction of 8-hydroxy-quinoline with 1,2-phenyl-enediamine in methanol and recrystallized from toluene. The compound contains three essentially planar ring systems: the benzimidazole ring (r.m.s. deviation = 0.039 Å) and two 8-hydroxy-quinoline rings (r.m.s. deviations of 0.0056 Å in both rings). The benzimidaz...

In the title compound, C(19)H(13)N(3)O, the dihedral angle between the two quinoline systems is 11.54 (3)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N and C-H⋯O hydrogen bonds, with N-H⋯N being bifurcated towards the two N atoms of the two quinoline rings. In the crystal, there are weak intermolecular π-π inter-actions present involving the quinoline rings [centroid-cent...

In the title compound, C(15)H(12)ClN(3)O, the quinoline ring system is essentially planar, with a maximum deviation of 0.017 (1) Å. The crystal packing is stabilized by π-π stacking inter-actions between the quinoline rings of adjacent mol-ecule, with a centroid-centroid distance of 3.5913 (8) Å. A weak C-H⋯π contact is also observed between mol-ecules.
