In the solid state, the title compound, C 25 H 16 Br 2 O 2 , shows significant deviations of the fluorene ring system from planarity. A layered hydrogen-bonded structure is formed that may serve as a model for the solid-state structure of phenol-functionalized polyfluorene.

The title compound, C 29 H 24 O 2 , has mirror symmetry with the cyclopropane C atoms lying on the mirror plane. The fluorene system is essentially planar and makes dihedral angles of 91.43 (4) and 23.50 (6) with the cyclopropane and substituted benzene rings, respectively.
