N′-Benzyl­idene-2-chloro-N-(4-chloro­phen­yl)acetohydrazide

In the title compound, C₁₅H₁₂Cl₂N₂O, the atoms not making up the chloro­benzene ring are approximately coplanar (r.m.s. deviation = 0.073 Å). The dihedral angle between these 13 atoms and the chloro­benzene ring is 67.37 (10)°. The C=O and Csp²—Cl groups are almost eclipsed [Cl—C—C=O = −6.5 (3)°]. In the crystal, C(6) chains linked by C—H...O hydrogen bonds result in [100] chains.

5-(4-Chloro­phen­oxy)-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde

In the title compound, C₁₇H₁₃ClN₂O₂, the phenyl and chloro­benzene rings are inclined to the central pyrazole ring at 40.84 (9) and 65.30 (9)°, respectively. In the crystal, pairs of C—H...π inter­actions link the mol­ecules into inversion dimers and C—H...O hydrogen bonds link these dimers into columns extended in [010]. The crystal packing exhibits short inter­molecular O...Cl contacts of 3.0913 (16) Å.
