title: 3,3'-Dibromo-5,5'-di-tert-butyl-2,2'-dimethoxy-biphen-yl.
abstract: The title compound, C(22)H(28)Br(2)O(2), crystallizes in a staggered arrangement to minimize the inter-actions of its ortho substituents, with a dihedral angle of 84.2 (3)° between the two aromatic rings. Short C-H⋯O hydrogen-bonding inter-actions between meth-oxy groups result in a one-dimensional polymeric chain of mol-ecules lying parallel to the b axis. One tert-butyl group is disordered equally over two positions.
