Abstract

The title mol­ecule, C15H15Br2, has crystallographic m2m site symmetry. As a result, all atoms, except for those of the methyl groups, are exactly coplanar. In the crystal structure, there are weak π–π inter­actions with a centroid–centroid distance of 3.8409 (15) Å between symmetry-related mol­ecules, which stack along the c axis.
