The title compound, C 19 H 16 N 2 , crystallizes with two molecules in the asymmetric unit related by a non-crystallographic plane of symmetry. The three fused rings of the fluorene system are almost coplanar. The cyanoethanoic groups display extended conformations and are nearly perpendicular to th
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.
