title: 1-(2,4-Dichloro-phen-yl)-5-(2-nitro-anilino)-1H-pyrazole-4-carbonitrile.
abstract: In the title compound, C(16)H(9)Cl(2)N(5)O(2), the folded mol-ecular conformation is characterized by a dihedral angle between the two benzene rings of 74.03 (5)°. An intra-molecular N-H⋯O hydrogen bond is observed between the H atom of the amide group and a nitro-group O atom. Inter-molecular C-H⋯O and N-H⋯N hydrogen bonds feature in the crystal packing.
