Abstract: In the title compound, C 24H 15Cl 2N 3O 3, the C=C double bond is E configured. The 1-phenyl-1H-pyrazole moiety is roughly planar (r.m.s. deviation of all fitted non-H atoms = 0.0780 ), but the mean planes of the two components are inclined at an angle of 9.95 (7) . The mean plane defined by the non-H atoms of the 1H-pyrazole ring encloses angles of 9.95 (7), 24.54 (6) and 43.02 (6) with the mean planes of the different benzene rings. In the crystal, C - H?O contacts are present and result in the formation of a double-layer two-dimensional network lying parallel to (110). The shortest inter-centroid distance between two aromatic systems is 3.5455 (7) and is apparent between two pyrazole systems. Further ?-? interactions are manifest between a pair of 4-nitrophenyl rings [centroid-to-centroid distance = 3.6443 (7) ] and a pair of 2,4-dichlorophenyl rings [centroid-to-centroid distance = 3.7797 (7) ].
