The aim of the study is to explore the crystal structure and performe Hirshfeld surface analysis of l-(4-chlorophenyl)-5-{4-[(2-methylphenyl)methoxy]phenyl}-1H-pyrazole. In the title compound, C23H19C1N2O, the 4-chlorophenyl, 2-methylphenyl and benzene rings are oriented with dihedral angles of 71.22(10), 31.82(9) and 59.76(9)°, respectively, with respect to the pyrazole ring. Pairs of molecules are linked by intermolecular C-H⋯O hydrogen contacts with R22(8) ring motifs forming sheets lying parallel to (100). Furthermore C-H⋯π interactions also contribute to stabilizing the molecular packing. A Hirshfeld surface analysis has been used to confirm and quantify the supramolecular interactions which indicate that the most important contributions for the crystal packing are from H⋯H (42.5%) and H⋯C/C⋯H (35%) and H⋯Cl/Cl⋯H (12%) interactions.
Crystal structure and theoretical study of (2E)-1-[4-hydroxy-3-(morpholin-4-ylmethyl)phenyl]-3-(thiophen-2-yl)prop-2-en-1-one
(2018-01-01) Yesilyurt F.; Aydin A.; Gul H.; Akkurt M.; Ozcelik N.
In the title compound, C18H19NO3S, the morpholine ring adopts a chair conformation. The thiophene ring forms dihedral angles of 26.04 (9) and 74.07 (10)° with the benzene ring and the mean plane of the morpholine ring, respectively. The molecular conformation is stabilized by an O - H⋯N hydrogen bond. In the crystal, molecules are connected through C - H⋯O hydrogen bonds, forming wave-like layers parallel to the ab plane, which are further linked into a three-dimensional network by C - H⋯π interactions involving the benzene rings and the methylene H atoms of the morpholine rings.
