2,7-Dibromo-9,9-dimethyl-9H-fluorene.

The title mol-ecule, C(15)H(15)Br(2), 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 inter-actions with a centroid-centroid distance of 3.8409 (15) Šbetween symmetry-related mol-ecules, which stack along the c axis.
