(E)-2-acetyl-4-(phenyldiazenyl) phenol 

Iskeleli, Nazan Ocak; Albayrak, Cigdem; Agar, Erbil (Int Union Crystallography, 2006)
The molecule of the title compound, C14H12N2O2, is nearly planar and displays a trans configuration with respect to the N=N double bond, as found for other diazene derivatives. There is an intramolecular O-H center dot ...

(E)-4-[(4-chlorophenyl)diazenyl]-2-isopropylphenol 

Atalay, Sehriman; Petek, Hande; Iskeleli, Nazan Ocak; Agar, Erbil (Int Union Crystallography, 2006)
In the title compound, C15H15ClN2O, the aromatic rings adopt a trans configuration with respect to the N = N bond, as found for other diazene derivatives. The crystal structure is stabilized by intermolecular O - H center ...

Anchor Effect on Pedal Motion Observed in Crystal Phase of an Azobenzene Derivative 

Karabiyik, Hasan; Petek, Hande; Iskeleli, Nazan Ocak; Albayrak, Cigdem; Agar, Erbil (Springer/Plenum Publishers, 2011)
Some molecules having a molecular skeleton similar to that of stilbenes and azobenzenes show orientational disorder in the crystals due to pedal motion. Heretofore, the orientational disorder through pedal motion has been ...
