In the title compound, C25H19NO, the quinoline ring system is approximately planar, with a maximum deviation of 0.32 (1) Å, and forms dihedral angles of 80.74 (3) and 81.71 (4)° with the two phenyl rings. In the crystal. molecules are stacked along the b axis by way of a C - H⋯π interaction and a weak π-π interaction between the pyridine and phenyl rings with a centroid-centroid distance of 3.6924 (5) Å.

Acta Crystallographica Section E Structure Reports Online

The title compound, C10H10N2O, crystallizes with two independent molecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two molecules are 39.57 (14) and 41.95 (13)°. The two molecules are each connected to neighbouring molecules by pairs of inter-molecular O-H⋯N hydrogen bonds, forming dimers with R 22(8) ring motifs. These dimers are further linked into R44(10) ring motifs by inter-molecular N-H⋯O hydrogen bonds, forming chains along [101]. The crystal structure is further stabilized by a C-H⋯π inter-action.

4-Methyl-5-phenyl-1H-pyrazol-3-ol

In the title compound, C27H20ClNO, the quinoline ring forms a dihedral angle of 62.53 (5)° with the substituent benzene ring. In the crystal, inter-molecular C - H⋯Cl inter-actions link the mol-ecules into chains along the b axis. Inter-molecular C - H⋯N and C - H⋯O hydrogen bonds further consolidate the structure into a three-dimensional network. The unit cell contains four solvent-accessible voids, each with a volume of 35 Å3, but no significant electron density was found in them.

(2E,4E)-1-(6-Chloro-2-methyl-4-phenyl-3-quinolyl)-5-phenylpenta-2,4-dien-1-one

In the title compound, C26H20ClNO2, the quinoline ring system is approximately planar with a maximum deviation of 0.028 (2) Å and forms a dihedral angle of 73.84 (5)° with the phenyl ring. Two neighbouring mol-ecules are arranged into a centrosymmetric dimer through a pair of inter-molecular C-H⋯Cl inter-actions. A pair of inter-molecular C-H⋯O hydrogen bonds link two methoxy-phenyl groups into another centrosymmetric dimer, generating an R 22(8) ring motif. The structure is further stabilized by C-H⋯π inter-actions.
