Crystal structure of (4Z)-4-[(2E)-3-(2-chlorophenyl)-1-hydroxyprop-2-en-1-ylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

Crystal structure of (4Z)-4-[(2E)-3-(2-chlorophenyl)-1-hydroxyprop-2-en-1-ylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

In the title compound, C19H15ClN2O2, the pyrazole ring is almost planar (r.m.s. deviation = 0.002 Å) and subtends dihedral angles of 5.31 (16) and 1.86 (16)° with the phenyl and chlorobenzene rings, respectively. An intramolecular O—H...O hydrogen bond closes an S(6) ring and a short C—H...O contact...
