2′,7′-Dibromospiro[cyclopropane-1,9′-fluorene]
Abstract
In the title compound, C15H10Br2, each molecule is situated on special postion mm, so the asymmetric unit contains one-quater of a molecule. The 2,7-dibromo-9H-fluorene fragment and three spirocyclopropane C atoms lie on different planes, which are perpendicular to each other. In the crystal, π–π interactions between aromatic rings [intercentroid distance = 3.699 (3) Å] pack the molecules into stacks extending in [001].
