title: 2',7'-Di-bromo-spiro-[cyclo-propane-1,9'-fluorene].
abstract: In the title compound, C15H10Br2, each mol-ecule is situated on special postion mm, so the asymmetric unit contains one-quater of a mol-ecule. The 2,7-di-bromo-9H-fluorene fragment and three spiro-cyclo-propane C atoms lie on different planes, which are perpendicular to each other. In the crystal, π-π inter-actions between aromatic rings [inter-centroid distance = 3.699 (3) Å] pack the mol-ecules into stacks extending in [001].
