9,9-Dibutyl-9H-fluorene-2-carbonitrile
The fluorene fragment of the title compound, C(22)H(25)N, is essentially planar, with an r.m.s deviation of the five-membered ring of 0.005 (2) Å. The dihedral angle between this ring and the outer benzene rings are 1.5 (2) and 0.7 (2)° while that between the benzene rings is 2.1 (2)°. The cyano group makes an angle of 0.3 (2)° with the attached benzene ring.

THE TITLE COMPOUND [SYSTEMATIC NAME: 9-(9H-fluoren-3-yl)-9H-fluorene], C(26)H(18), was obtained unintentionally as the product of the synthesis of a compound based on fluorene-thio-phene units. The two fluorene rings are connected through C atoms in the 3- and 9'-positions, and the dihedral angle between the mean planes of the two fluorene units is 78.57 (6)°.

The title compound, C(29)H(24)Cl(2)O(2), a fluorene derivative, features a C atom that is connected to four phenyl-ene rings, two of which are almost coplanar (r.m.s. deviation = 0.035 Å) as they belong to the fluorene system. The other two rings are aligned at angles of 67.5 (5) and 85.5 (5)° with respect to the pair. The O and Cl atoms of the -OCH(2)CH(2)Cl- units adopt a gauche conformation ...

In the title compound, C(31)H(22)O(2), the bond angle at the C atom belonging to the five-membered ring of the fluorene system is opened to 112.64 (12)°. The two benzene rings are twisted with respect to the fluorene ring system at dihedral angles of 72.81 (6) and 81.83 (6)°. One C(ar-yl)-O-C-C fragment is extended, with a C-O-C-C torsion angle of -178.77 (13)°, but the other C(ar-yl)-O-C-C f...

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.
