3,9′-Bi(9H-fluorene) [PDF]
The title compound [systematic name: 9-(9H-fluoren-3-yl)-9H-fluorene], C26H18, was obtained unintentionally as the product of the synthesis of a compound based on fluorene–thiophene units. The two fluorene rings are connected through C atoms in

9-Chloromethyl-9-[(9H-fluoren-9-yl)methyl]-9H-fluorene [PDF]
In the title compound, C(28)H(21)Cl, the dihedral angle between the two fluorene ring systems is 71.97 (4)°. There is an intra-molecular C-H⋯Cl hydrogen bond. In the crystal structure, the centroid-to-centroid distance between stacked fluorene ring systems is ca 4.22 Å, which indicates that there are no π-π stacking inter-actions between them.

Dispiro[fluorene-9,5′-[1,2,3,4]tetrathiane-6′,9′′-fluorene] [PDF]
The tetrathiane ring of the title compound, C26H16S4, has a chair conformation and the molecule has approximate C2 symmetry. Each of the two fluorene ring systems is virtually planar, with the ring planes intersecting at an angle of 67.58 (5) degrees. This novel compound has been formed as a side product from the treatment of 9H-fluorene-9-thione with ...
