3,5-Dibromo-2-hydroxybenzaldehyde

Abstract

The title compound, C7H4Br2O2, exhibits a layer packing structure via weak π–π stacking interactions [centroid–centroid distances between adjacent aromatic rings are 4.040 (8) and 3.776 (7) Å]. Molecules in each layer are linked by intermolecular O—H...O hydrogen bonding and Br...Br interactions [3.772 (4) Å]. There are two molecules in the asymmetric unit.
