(4-Chloro-phen-yl)[1-(4-methoxy-phen-yl)-3-(5-nitro-2-fur-yl)-1H-pyrazol-4-yl]methanone.

ABSTRACT: In the title compound, C(21)H(14)ClN(3)O(5), an intra-molecular C-H⋯O hydrogen bond generates an S(7) ring motif and the furan and pyrazole rings are almost coplanar, making a dihedral angle of 1.98 (5)°. The pyrazole ring is inclined at dihedral angles of 47.59 (4) and 7.27 (4)° to the chloro-phenyl and methoxy-phenyl groups, respectively. The nitro group is almost coplanar to its attached furan ring [dihedral angle = 2.03 (12)°]. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. The crystal structure also features short inter-molecular O⋯N [2.8546 (12) Å] and Cl⋯O [3.0844 (9) Å] contacts as well as aromatic π-π stacking inter-actions [centroid-centroid distance = 3.4367 (6) Å].
