Crystal structure of (4Z)-4-[(2E)-3-(4-chlorophenyl)-1-hydroxyprop-2-en-1-ylidene]-5-methyl-2-phenyl-1H-pyrazol-5(4H)-one
In the the asymmetric unit of the title compound, C19H15ClN2O2, there are two symmetry-independent molecules, which adopt similar conformations. The largest difference is observed in the dihedral angles between the phenyl and the pyrazole fragments [17.00 (12) and 23.42 (10)°]. A strong intramolecul...

| description |
In the the asymmetric unit of the title compound, C19H15ClN2O2, there are two symmetry-independent molecules, which adopt similar conformations. The largest difference is observed in the dihedral angles between the phenyl and the pyrazole fragments [17.00 (12) and 23.42 (10)°]. A strong intramolecular O—H...O hydrogen bond with the S (6) motif is observed in both molecules. Pairs of π–π stacking interactions between the phenyl groups [centroid–centroid distances = 3.6627 (13) and 3.7156 (14) Å] assemble the molecules into two types of centrosymmetric dimers. Weak C—H...O interactions connect molecules into chains along the b axis. |
