1,1´-(9-Octyl-9H-carbazole-3,6-di­yl)diethanone (2010)
Saeed, Aamer ; Kazmi, Madiha ; Samra, Shahid Ameen ; Irfan, Madiha ; Bolte, Michael
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.
(Biphenyl-4-yl)(phen­yl)methanone (2010)
Saeed, Aamer ; Samra, Shahid Ameen ; Irfan, Madiha ; Bolte, Michael
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.
4-Chloro-N-m-tolylbenzamide (2009)
Saeed, Aamer ; Irfan, Madiha ; Bolte, Michael
In the title compound, C14H12ClNO, the dihedral angle between the two aromatic rings is 11.29 (15)°. The crystal packing is stabilized by N-H...O hydrogen bonds linking the molecules into chains running along the c axis. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.004 Å; R factor = 0.066; wR factor = 0.178; data-to-parameter ratio = 13.7.
