title: Crystal structure of 1-(2,4-di-nitro-phen-yl)-3,5-diphenyl-1H-pyrazole.
abstract: In the title mol-ecule, C21H14N4O4, the phenyl rings make dihedral angles of 39.61 (8) and 9.4 (1)°, respectively, with the central pyrazole ring. The dihedral angle between the pyrazole and di-nitro-phenyl rings is 46.95 (5)°. In the crystal, mol-ecules pack in helical stacks parallel to the a axis aided by weak C-H⋯O inter-actions.
