4,4'-Dibromo-7,7'-dimeth-oxy-1,1'-spiro-biindane.

ABSTRACT: In the title compound, C(19)H(18)Br(2)O(2), the dihedral angle between the two benzene rings of the spiro-biindane molecule is 70.44 (8)°. In the crystal, mol-ecules are inter-connected along the c axis by C-H⋯O hydrogen bonds and π-π stacking [centroid-centroid distance = 3.893 (2) Å] inter-actions, forming an infinite chain structure. The chains are further inter-connected through another set of C-H⋯O hydrogen bonds, forming layers approximately parallel to the bc plane.
