Abstract
The X-ray structure analyses of 4-hydroxy-1-methylquinolin-2(1H)-one (1), 6-ethyl-4-hydroxy-2H-pyrano[3,2-c]quinoline-2,5(6 H)-dione (2), (E)-4-(2-benzylidene-hydrazineyl)quinolin-2(1H)-one (3), and diethyl (E)-2-(2-(1-methyl-2-oxo-1,2-dihydroquinolin-4-yl)hydrazineylidene)-succinate (4), were carried out. The aforementioned compounds showed strong intramolecular hydrogen bonds which play important roles in the crystal packing of them.
期刊介绍：
Journal of Chemical Crystallography is an international and interdisciplinary publication dedicated to the rapid dissemination of research results in the general areas of crystallography and spectroscopy. Timely research reports detail topics in crystal chemistry and physics and their relation to problems of molecular structure; structural studies of solids, liquids, gases, and solutions involving spectroscopic, spectrometric, X-ray, and electron and neutron diffraction; and theoretical studies.
