title: 5-Bromo-2-[5-(4-nitro-phen-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]pyrimidine.
abstract: 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 nitro-benzene unit is almost perpendicular to the attached pyrazoline ring, as indicated by the dihedral angle of 84.61 (8)°. In the crystal structure, inter-molecular C-H⋯N contacts link the mol-ecules into dimers in an anti-parallel 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 inter-molecular π-π inter-actions [range of centroid-centroid distances = 3.5160 (11)-3.6912 (11) Å].
