The title compound, C(12)H(8)Cl(2)N(4)O, was synthesized by the reaction of 5-amino-1-(4-chloro-phen-yl)-1H-pyrazole-3-carbonitrile and 2-chloro-acetyl chloride. The dihedral angle between the pyrazole and benzene rings is 30.7 (3)°. In the crystal structure, strong N-H⋯O hydrogen bonds link the mol-ecules into chains along [001]. C-H⋯N hydrogen bonds are also present.
