[3-(5-Nitro-2-furyl)-1-phenyl-1H-pyrazol-4-yl](phenyl)methanone

In the title pyrazole compound, C(20)H(13)N(3)O(4), an intramolecular C-H center dot center dot center dot 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) angstrom, respectively] are coplanar with each other, forming a dihedral angle of 3.06 (10)degrees. The pyrazole ring forms dihedral angles of 8.51 (9) and 56.81 (9)degrees 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)degrees. In the crystal packing, intermolecular C-H center dot center dot center dot O hydrogen bonds link adjacent molecules into two-molecule-wide chains along the a axis. The crystal packing is further stabilized by weak intermolecular C-H center dot center dot center dot pi and pi-pi interactions [centroid-centroid distance = 3.4441 (10) angstrom].
