4,4,5,5-Tetra-methyl-2-[1,3,6,8-tetra-bromo-7-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)pyren-2-yl]-1,3,2-dioxaborolane.


ABSTRACT: The complete mol-ecule of the title compound, C(28)H(28)B(2)Br(4)O(4), is generated by the application of a centre of inversion. In the mol-ecule, the BO(2) plane is perpendicular to that through the pyrene ring [dihedral angle = 86.27?(13)°]. In the crystal, mol-ecules stack into columns along the b axis, the closest contact between these being of the type C-Br??.
