1-[5-(4-Bromophenyl)-3-(4-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl]butan-1-one

In the title compound, C(19)H(18)BrFN(2)O, the benzene rings form dihedral angles of 5.38 (7) and 85.48 (7)° with the mean plane of the 4,5-dihydro-1H-pyrazole ring (r.m.s. deviation = 0.0849 Å), which approximates to an envelope conformation with the -CH(2)- group as the flap. The dihedral angle between the benzene rings is 82.86 (7)°. In the crystal, C-H⋯F and C-H⋯O hydrogen bonds link the mo...

In the title compound, C(17)H(15)ClN(2)O(2), the benzene rings form dihedral angles of 89.56 (5) and 5.87 (5)° with the mean plane of the pyrazoline ring (r.m.s. deviation = 0.084 Å). The dihedral angle between the two benzene rings is 87.57 (5)°. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds into a helical chain along the c axis. Between the chains weak C-H⋯N and C-H⋯...

In the title compound, C(18)H(17)ClN(2)O(2), the benzene rings form dihedral angles of 6.69 (6) and 74.88 (5)° with the 4,5-dihydro-1H-pyrazole ring. The benzene rings form a dihedral angle of 76.67 (5)° with each other. In the crystal, mol-ecules are linked via bifurcated (C,C)-H⋯O hydrogen bonds into chains along [010]. The crystal structure is further consolidated by C-H⋯π inter-actions.
