title: [3-(5-Nitro-2-fur-yl)-1-phenyl-1H-pyrazol-4-yl](phen-yl)methanone.
abstract: In the title pyrazole compound, C(20)H(13)N(3)O(4), an intra-molecular C-H⋯O hydrogen bond generates a seven-membered ring, producing an S(7) ring motif. The essentially planar furan and pyrazole rings [maximum deviations of 0.002 (1) and 0.007 (1) Å, respectively] are coplanar with each other, forming a dihedral angle of 3.06 (10)°. The pyrazole ring forms dihedral angles of 8.51 (9) and 56.81 (9)° with the two benzene rings. The nitro group is coplanar with the attached furan ring, as indicated by the dihedral angle of 2.5 (3)°. In the crystal packing, inter-molecular C-H⋯O hydrogen bonds link adjacent mol-ecules into two-mol-ecule-wide chains along the a axis. The crystal packing is further stabilized by weak inter-molecular C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.4441 (10) Å].
