title: (2E)-1-(2,4-Dichloro-phen-yl)-3-[3-(4-nitro-phen-yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one.
abstract: In the title compound, C(24)H(15)Cl(2)N(3)O(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 Å), 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) Å and is apparent between two pyrazole systems. Further π-π inter-actions are manifest between a pair of 4-nitro-phenyl rings [centroid-to-centroid distance = 3.6443 (7) Å] and a pair of 2,4-dichloro-phenyl rings [centroid-to-centroid distance = 3.7797 (7) Å].
