6-Chloro-3-[5-(4-fluorophenyl)-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl]-2-methyl-4-phenylquinoline
In the title compound, C(31)H(23)ClFN(3), the pyrazole ring forms dihedral angles of 72.75 (7), 18.08 (9) and 86.26 (9)° with the quinoline ring system, the phenyl ring and the fluoro-phenyl ring, respectively. In the crystal, inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into chains propagating along the c axis. The crystal structure is further stabilized by C-H⋯π inter-actions.

In the title compound, C(18)H(14)ClNO, the quinoline ring system is approximately planar with a maximum devation of 0.022 (1) Å and forms a dihedral angle of 62.70 (3)° with the phenyl ring. In the crystal, pairs of C-H⋯O inter-molecular hydrogen bonds link neighbouring mol-ecules into inversion dimers, forming R(2) (2)(14) ring motifs. These inversion dimers are stacked along the b axis. The s...
