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
Abstract
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.
