5-Bromo-2-[5-(4-nitro­phen­yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]pyrimidine

In the title pyrazoline compound, C(19)H(14)BrN(5)O(2), the essentially planar pyrazoline and pyrimidine rings [maximum deviations = 0.013 (1) and 0.009 (1) Å, respectively] are inclined slightly to one another, making a dihedral angle of 10.81 (10)°. The nitro­benzene unit is almost perpendicular to the attached pyrazoline ring, as indicated by the dihedral angle of 84.61 (8)°. In the crystal structure, inter­molecular C—H⋯N contacts link the mol­ecules into dimers in an anti­parallel manner. These dimers are further linked into one-dimensional chains along the b axis via C—H⋯O contacts. The crystal structure is consolidated by three different inter­molecular π–π inter­actions [range of centroid–centroid distances = 3.5160 (11)–3.6912 (11) Å].
