The title compound, C(18)H(28)N(4)O(6), crystallizes with two mol-ecules 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 mol-ecules. A strong intra-molecular N-H⋯O hydrogen bond between the amino and nitro groups occurs in each mol-ecule. The crystal structure features two symmetry-independent polymeric chains along [010] generated by N-H⋯O hydrogen bonds between the amide groups. ...[more]
