2-Methoxy-N-[(S)-3-methylbutan-2-yl]-6-{[(S)-3-methylbutan-2-yl]amino}-3,5-dinitrobenzamide

The title compound, C18H28N4O6, crystallizes with two molecules in the asymmetric unit which differ slightly in conformation. The dihedral angle between the amide plane and the benzene ring are 72.6 (2) and 66.8 (2)° in the two molecules. A strong intramolecular N—H...O hydrogen bond between the amino and nitro groups occurs in each molecule. The crystal structure features two symmetry-independent polymeric chains along [010] generated by N—H...O hydrogen bonds between the amide groups
