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.

The asymmetric unit of title compound, C(36)H(27)As, contains two crystallographically independent mol-ecules, A and B, with similar conformations. The two phenyl rings of each biphenyl unit are twisted slightly away from each other with dihedral angles of 6.0 (2), 27.7 (3) and 33.4 (2)° in mol-ecule A and 5.7 (3), 27.5 (2) and 33.0 (2)° in mol-ecule B. The As-bonded phenyl rings make dihedral ...

In the title compound, C(19)H(14)O, the dihedral angle between the two aromatic rings of the biphenyl residue is 8.0 (3)° and the dihedral angle between the two rings connected by the carbonyl C atom is 51.74 (18)°. There are no short C-H⋯O contacts in the crystal structure.
متن کامل9,9-Bis[4-(2-chloroethoxy)phenyl]-9H-fluorene
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 ...
