Crystallographic and Conformational Analysis of [(Z)-2-ethoxy-6-[(2-hydroxyphenylamino)methylene]cyclohexa-2,4-dienone]
Özet
The single crystal X-ray diffraction analysis of the title compound, C15H15NO3, shows that the structure is adopted to its NH tautomeric form and crystallizes in the orthorhombic space group P bcn with a = 21.2424(15) angstrom, b = 12.7696(9) angstrom, c = 9.3605(10) angstrom, Z = 8, V = 2539.1(4) angstrom(3), D-c = 1.346 g/cm(3). The molecular conformation in the crystal is stabilized by an intramolecular H-bond and the crystal structure is stabilized by the bifurcated O-H center dot center dot center dot O type intermolecular H-bonds. In order to understand the effects on conformational flexibility of the title molecule, molecular energy profile was calculated as a function of the selected torsion angle by means of AM1 semi-empirical method.
