5-Amino-1-(4-nitro­phen­yl)-1H-pyrazole-3-carbonitrile

The title compound, C₁₀H₇N₅O₂, was synthesized by the reaction of 4-nitro­aniline and 2,3-dicyano­propionic acid ethyl ester. In the crystal, N—H...O and C—H...O hydrogen bonds link the mol­ecules, forming a three-dimensional network.

2-Chloro-N-{3-cyano-1-[2,6-dichloro-4-(trifluoro­meth­yl)phen­yl]-1H-pyrazol-5-yl}acetamide

The title compound, C₁₃H₆Cl₃F₃N₄O, was synthesized by the reaction of 5-amino-1-[2,6-dichloro-4-(trifluoro­meth­yl)phen­yl]-1H-pyrazole-3-carbonitrile and 2-chloro­acetyl chloride. The five-membered pyrazole ring makes a dihedral angle of 71.5 (3)° with the benzene ring. The –CF₃ 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 inter­actions involving the carbonyl and cyano groups as acceptors.
