%X In the title compound, C21H14ClN3O5, an intramolecular C¡ªH...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)¡ã. The pyrazole ring is inclined at dihedral angles of 47.59 (4) and 7.27 (4)¡ã to the chlorophenyl and methoxyphenyl groups, respectively. The nitro group is almost coplanar to its attached furan ring [dihedral angle = 2.03 (12)¡ã]. In the crystal, intermolecular C¡ªH...O hydrogen bonds link the molecules into a three-dimensional network. The crystal structure also features short intermolecular O...N [2.8546 (12)  ] and Cl...O [3.0844 (9)  ] contacts as well as aromatic ¦Ð¨C¦Ð stacking interactions [centroid¨Ccentroid distance = 3.4367 (6)  ].
