title: 5-Amino-1-(4-nitro-phen-yl)-1H-pyrazole-3-carbonitrile.
abstract: The title compound, C(10)H(7)N(5)O(2), was synthesized by the reaction of 4-nitro-aniline and 2,3-dicyano-propionic acid ethyl ester. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.
