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
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.
