Abstract
In the title compound, C20H16Br2, the terminal phenyl groups are twisted away from the central ring by approximately 55 and −125° (average of four dihedral angles each), respectively. The crystal structure is stabilized by a combination of intermolecular and intramolecular interactions including intermolecular π–π stacking interactions [C atoms of closest contact = 3.423 (5) Å].
