1-(2,4-Dichlorophenyl)-5-(2-nitroanilino)-1H-pyrazole-4-carbonitrile
Abstract
In the title compound, C16H9Cl2N5O2, the folded molecular conformation is characterized by a dihedral angle between the two benzene rings of 74.03 (5)°. An intramolecular N—H...O hydrogen bond is observed between the H atom of the amide group and a nitro-group O atom. Intermolecular C—H...O and N—H...N hydrogen bonds feature in the crystal packing.
