چکیده
The title compound, C(7)H(4)BrNO(3), was isolated as a by-product while attempting to prepare a diselenide. There is a close intra-molecular Br⋯O contact [2.984 (2) Å]. The mol-ecules form loosely associated dimers held together by weak inter-molecular Br⋯O inter-actions with the nitro O atoms [Br⋯O = 3.179 (3) Å]. As a result of these inter-actions, there is also a close Br⋯Br inter-molecular contact [3.8714 (6) Å]. In addition, there are weak inter-molecular C-H⋯O inter-actions. The combination of these inter-actions produces sheets which propagate in the (210) and (10) directions perpendicular to c.

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.
