چکیده
The hydroxyl group in each of the two independent mol-ecules of the title compound, C(7)H(5)NO(4), participates in two O-H⋯O hydrogen bonds, viz. one intra-molecular bond to the nitro group and one inter-molecular bond to the aldehyde group of the same mol-ecule in the next unit, resulting in a linear chain structure. The dihedral angle between the aromatic ring and the nitro group is 10.9 (3)° in one mol-ecule and 9.9 (2)° in the other.

The title compound, C(7)H(5)NO(4), is essentially planar, with a maximum deviation from the mean plane of 0.0116 (11) Å for the hydr-oxy O atom. The mol-ecular and crystal structure are stabilized by intra- and inter-molecular inter-actions. An intra-molecular O-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. The C-H⋯O inter-actions result in the formation of C(5)...

In the title compound, C(13)H(9)N(5)O(7), one of the nitro groups is twisted away from the attached benzene ring by 16.21 (8)°. The dihedral angle between the two benzene rings is 4.63 (1)°. The mol-ecular structure is stabilized by intra-molecular N-H⋯O and O-H⋯N hydrogen bonds which generate an S(6) ring motif. The mol-ecules pack as layers parallel to the ab plane; mol-ecules of adjacent lay...

The title compound, C(7)H(5)NO(4), isolated from the leaves of Actephila merrilliana, is essentially planar (r.m.s. deviation = 0.026 Å). The conformation is supported by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, C-H⋯O inter-actions and aromatic π-π stacking [centroid-centroid distance = 3.754 (4) Å] help to establish the packing.
