چکیده
The asymmetric unit of the title compound, C(8)H(7)N(3)O(5), contains two independent mol-ecules in which the amide plane is oriented at dihedral angles of 29.82 (2) and 31.17 (2)° with respect to the benzene ring. In the crystal, mol-ecules are connected via inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b axis.

The title compound, C(9)H(9)N(3)O(6), was synthesized by the condensation of methyl 3,5-dinitro-benzoate and 2-amino-ethanol. The non-centrosymmetric space group results in the formation of pseudo-chiral helices in the crystal structure, which exhibits a layer packing structure involving intra-molecular N-H⋯O and O-H⋯O inter-actions.

The title mol-ecule, C(13)H(8)BrN(3)O(5), is slightly twisted, with the dihedral angle between the two benzene rings being 5.9 (1)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into one-dimensional chains running along [101]. Further stabilization of the crystal structure is provided by π-π inter-actions [shortest centroid-centroid distance = 3.6467 (17) Å].

In the title compound, C(19)H(25)N(3)O(5), the benzene ring is not coplanar with the amide group [dihedral angle = 61.90 (5)°]. The cyclo-hexyl rings are in chair conformations. There is a strong inter-molecular inter-action between the C=O group of the amide group and the nitro group of an adjoining mol-ecule, with a short O⋯N distance of 2.7862 (17) Å. In the crystal, C-H⋯O inter-actions occu...
