Abstract

The title compound, C(13)H(6)Cl(3)F(3)N(4)O, was synthesized by the reaction of 5-amino-1-[2,6-dichloro-4-(trifluoro-meth-yl)phen-yl]-1H-pyrazole-3-carbonitrile and 2-chloro-acetyl chloride. The five-membered pyrazole ring makes a dihedral angle of 71.5 (3)° with the benzene ring. The -CF(3) group is disordered by rotation, and the F atoms are split over two sets of sites with occupancies of 0.59 (2) and 0.41 (2). The crystal structure features weak C-H⋯O and N-H⋯N inter-actions involving the carbonyl and cyano groups as acceptors.
