title: 12,12'-[2,2'-Oxybis(ethane-2,1-di-yl)bis-(-oxy)]bis-[(R(p))-4-bromo-[2.2]paracyclo-phane].
abstract: The title compound, C(36)H(36)Br(2)O(3), was synthesized from (R(p))-4-bromo-12-hy-droxy[2.2]paracyclo-phane and oxydiethane-2,1-diyl bis-(4-methyl-benzene-sulfonate). The crystal packing exhibits a short O⋯Br inter-action [Br⋯O = 3.185 (3) Å] and a weak inter-molecular C-H⋯O contact.
