In the title compound, C18H14BrNO, the naphthalene ring system [maximum deviation = 0.015 (3) Å] forms a dihedral angle of 67.70 (10)° with the benzene ring. In the crystal, molecules are linked by N—HO hydrogen bonds into C(4) chains propagating in [100]. A C—HO interaction reinforces the chain connectivity, generating an R21(6) loop.

In the title compouund, C15H10F2O, the molecule exists in an E conformation with respect to the C=C bond [1.3382 (16) Å]. The dihedral angle between the fluoro-substituted benzene rings is 6.80 (6)° and the whole molecule is roughly planar (r.m.s. deviation for the non-H atoms = 0.069 Å). In the crystal, molecules are linked by C—HF and C—HO interactions into sheets lying parallel to the bc plane.

The asymmetric unit of the title compound, C20H14Cl3NO, consists of two independent molecules. In one molecule, the chlorinated benzene ring forms dihedral angles of 12.00 (9) and 77.04 (9)° with the phenyl rings. The dihedral angle between the phenyl rings is 80.37 (10)°. The corresponding dihedral angles for the other molecule are 26.34 (10), 62.98 (10) and 88.47 (11)°, respectively. One of the molecules features an intramolecular C—HO hydrogen bond, which forms an S(6) ring motif. In the crystal, molecules are linked by N—HO hydrogen bonds into [100] chains. The chains are further linked by C—HO and C—HCl hydrogen bonds into a three-dimensional network.

N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-2-[4-(methylsulfanyl)phenyl]acetamide
In the title compound, C20H21N3O2S, the 2,3-dihydro-1H-pyrazole ring is nearly planar (r.m.s. deviation = 0.023 Å) and forms dihedral angles of 16.96 (6) and 38.93 (6)° with the benzene and phenyl rings, respectively. The dihedral angle between the benzene and phenyl rings is 55.54 (6)°. The molecular conformation is consolidated by an intramolecular C—HO hydrogen bond, which forms an S(6) ring. In the crystal, inversion dimers linked by pairs of N—HOp (p = pyrazole) hydrogen bonds generate R22(10) loops. The dimers are linked by C—HO hydrogen bonds into sheets lying parallel to (100).
