- (Biphenyl-4-yl)(phenyl)methanone (2010)
- In the title compound, C19H14O, 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.
- 1,1´-(9-Octyl-9H-carbazole-3,6-diyl)diethanone (2010)
- The central structural element of the title compound, C24H29NO2, is a carbazole unit substituted with two acetyl residues and an octyl chain. The acetyl residues are nearly coplanar [dihedral angles = 5.37 (14) and 1.0 (3)°] with the carbazole unit which is essentially planar (r.m.s. deviation for all non-H atoms = 0.025 Å). The octyl chain adopts an all-trans conformation. The crystal packing is stabilized by C—H ... O hydrogen bonds.
