Abstract
In the title compound, C19H18N4O4, the nitrophenyl and phenyl rings are twisted by 67.0 (6) and 37.4 (4)°, respectively, with respect to the pyrazole ring plane [maximum deviation = 0.0042 (16) Å]. The dihedral angle between the mean planes of the phenyl rings is 59.3 (3)°. The amide group, with a C-N-C-C torsion angle of 177.54 (13)°, is twisted away from the plane of the pyrazole ring in an antiperiplanar conformation. In the crystal, N-H...O hydrogen bonds involving the carbonyl group on the pyrazole ring and the amide group, together with weak C-H...O interactions forming R22(10) graph-set motifs, link the molecules into chains along [100]. Additional weak C-H...O interactions involving the nitrophenyl rings further link the molecules along [001], also forming R22(10) graph-set motifs, thereby generating (010) layers.
