Abstract

The title 1:1 adduct, C(5)H(5)BrN(2)·C(7)H(6)O(3), contains two mol-ecules of each species in the asymmetric unit, with similar geometries. In the crystal, mol-ecules are linked to form extended chains along [100] by N-H⋯O, O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds. Adjacent chains are crosslinked via further N-H⋯O inter-actions into sheets lying parallel to (001). The crystal studied was an inversion twin with a 0.54 (2):0.46 (2) domain ratio.
