Abstract
In the title compound, C21H14ClN3O5, an intramolecular 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 chlorophenyl and methoxyphenyl groups, respectively. The nitro group is almost coplanar to its attached furan ring [dihedral angle = 2.03 (12)°]. In the crystal, intermolecular C—H⋯O hydrogen bonds link the molecules into a three-dimensional network. The crystal structure also features short intermolecular O⋯N [2.8546 (12) Å] and Cl⋯O [3.0844 (9) Å] contacts as well as aromatic π–π stacking interactions [centroid–centroid distance = 3.4367 (6) Å].
