3,3′′-Bis(9-hydroxyfluoren-9-yl)-1,1′:3′,1′′-terphenyl

Crystal structure of 2,2′′-bis­(2,7-di­chloro-9-hy­droxy-9H-fluoren-9-yl)-1,1′:4′,1′′-terphenyl tri­ethyl­amine trisolvate

In the title solvate, C44H26Cl4O2·3C6H15N, the asymmetric part of the unit cell comprises two halves of the diol mol-ecules, 2,2''-bis-(2,7-di-chloro-9-hy-droxy-9H-fluoren-9-yl)-1,1':4',1''-terphenyl, and three mol-ecules of tri-ethyl-amine, i. e. the diol mol-ecules are located on crystallographic symmetry centres. Two of the solvent mol-ecules are disordered over two positions [occupancy rati...

(Anthracen-9-yl)(piperidin-1-yl)­methanone

The title compound, C(20)H(19)NO, is a substructure of CP-640186, a potent inhibitor of mammalian acetyl-coenzyme A carboxyl-ases. In the crystal structure, the amide group forms a dihedral angle of 87.0 (1)° with the plane of the anthracene unit and the piperidine ring adopts a chair conformation. Mol-ecules are arranged into layers parallel to (100) and adjacent anthracene units within layers...

9-Chloro­methyl-9-[(9H-fluoren-9-yl)meth­yl]-9H-fluorene

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.
