4-(4-Chlorobenzyl)-5-methyl-2-phenyl- 1H-pyrazol-3(2H)-one
The five-membered ring of the title compound, C17H15ClN2O, is almost planar (r.m.s. deviation = 0.008 A ° ), and its phenyl subsitutent is aligned at 34.9 (1) with respect to this ring. The angle at the methylene C atom is opened to 116.4 (2). In the crystal, adjacent molecules are linked by an N—H O hydrogen bond, generating a linear ... إقراء المزيد
