N'-(2,4-Dinitrophenyl)benzohydrazide

A. Saeed, I. Arshad and U. Flörke

Abstract: In the title compound, C₁₃H₁₀N₄O₅, the aromatic ring planes are close to perpendicular [dihedral angle = 75.94 (5)°] and the C-N-N-C torsion angle is 88.7 (2)°. Both nitro groups lie close to their attached ring plane, with C-C-N-O torsion angles of 3.1 (2) and 5.3 (2)°. This allows for the formation of an intramolecular N-HO hydrogen bond, which closes an S(6) ring. In the crystal, N-HO hydrogen bonds link the molecules into zigzag chains extending along [100].
