Synthesis, spectroscopic, and molecular structure characterizations of some azo derivatives of 2-hydroxyacetophenone
(Elsevier, 2009)
Some novel azo compounds were prepared by the reaction of 2-hydroxyacetophenone with aniline and its substituted derivatives. The structures of synthesized azo compounds were determined by IR, UV-Vis, H-1 NMR and C-13 NMR ...
Crystallographic and conformational analyses of zwitterionic form of (E)-2-methoxy-6-[(2-morpholinoethylimino)methyl]phenolate
(Springer/Plenum Publishers, 2007)
The single crystal X-ray diffraction analysis of the title compound, C14H20N2O3, reveals that the structure is adapted to its zwitterionic form and R-2(2)(12) centrosymmetric dimers are formed by N+ - H center dot center ...

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