The title compound, C(26)H(25)Cl(3)N(6)O(4), was prepared by the reaction of (Z)-ethyl 3-amino-3-(4-chlorophenyl)-2-cyano-acrylate and 4-chloro-3-ethyl-1-methyl-1H-pyrazole-5-carbonyl chloride. The dihedral angles between the chlorobenzene and the two pyrazole rings are 59.8 (2) and 33.3 (2)degrees. The two pyrazole rings are oriented to each other at a dihedral angle of 84.7 (2)degrees. The crystal packing is governed by intermolecular C-H center dot center dot center dot O interactions, resulting in a three-dimensional network. The ethyl groups are disordered over two positions, with site-occupancy factors of 0.71/0.29 and 0.51/0.49.
