4,4,5,5-Tetra­methyl-2-[1,3,6,8-tetra­bromo-7-(4,4,5,5-tetra­methyl-1,3,2-dioxaborolan-2-yl)pyren-2-yl]-1,3,2-dioxaborolane

The complete mol­ecule of the title compound, C28H28B2Br4O4, is generated by the application of a centre of inversion. In the mol­ecule, the BO2 plane is perpendicular to that through the pyrene ring [dihedral angle = 86.27 (13)°]. In the crystal, mol­ecules stack into columns along the b axis, the closest contact between these being of the type C—Br⋯π.
