【 摘 要 】

The title compound, C20H16Cl2N2O3 (systematic name: 2-{[4-(2,4-di­chloro­benzo­yl)-1,3-di­methyl­pyrazol-5-yl}­oxy}-1-phenyl­ethan-1-one), is the benzoyl­pyrazole herbicide pyrazoxyfen. The asymmetric unit comprises two independent mol­ecules, A and B, in which the pyrazole ring makes dihedral angles of 80.29 (10) and 61.70 (10)° and 87.60 (10) and 63.92 (8)°, respectively, with the di­chloro­phenyl and phenyl rings. In the crystal, C—H⋯O and C—H⋯N hydrogen bonds, and C—H⋯π and π–π [3.646 (2) Å] inter­actions link adjacent mol­ecules, forming a two-dimensional network parellel to (011). In addition, the networks are linked by weak inter­molecular C—Cl⋯π [3.356 (2), 3.950 (2), 3.250 (2) and 3.575 (2) Å] inter­actions, resulting in a three-dimensional architecture.
