2,4-Dinitrobenzaldehyde hydrazone
Abstract
The title compound, C7H6N4O4, plays an important role in the synthesis of biologically active compounds. The planar hydrazone group is oriented at a dihedral angle of 8.27 (3)° with respect to the benzene ring. In the crystal structure, intermolecular N—H...O and N—H...N hydrogen bonds link the molecules.
