title: 3,5-Dibromo-2-hydroxy-benzaldehyde.
abstract: The title compound, C(7)H(4)Br(2)O(2), exhibits a layer packing structure via weak π-π stacking inter-actions [centroid-centroid distances between adjacent aromatic rings are 4.040 (8) and 3.776 (7) Å]. Mol-ecules in each layer are linked by inter-molecular O-H⋯O hydrogen bonding and Br⋯Br inter-actions [3.772 (4) Å]. There are two mol-ecules in the asymmetric unit.
