Structural, spectroscopic, and theoretical analysis of a molecular system based on 2-((2-(4- chlorophenylhydrazone)methyl)quinolone
(Universidad Nacional de Colombia, 2018-12-02)
A novel molecular system based on 2-((2-(4-chlorophenylhydrazone)methyl)quinoline (1-E) was synthesized. Interconversion of 1-E to its configurational isomer 1-Z was achieved using UV radiation (250 W Hg lamp). Such ...
(E)-5-[1-Hydroxy-3-(3,4,5-trimethoxyphenyl)allylidene]-1,3-dimethylpyrimidine-2,4,6-trione: Crystal structure and Hirshfeld surface analysis
(International Union of Crystallography, 2017-07-13)
In the title compound, C18H20N2O7, the dihedral angle between the aromatic rings is 7.28 (7)° and the almost planar conformation of the molecule is supported by an intramolecular O - H⋯O hydrogen bond, which closes an S(6) ...
