(4Z)-4-[(2E)-1-Hydr­oxy-3-(4-methoxy­phen­yl)prop-2-en­ylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

The title compound, C(20)H(18)N(2)O(4), is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxy­phenyl ring mean plane, and by 1.19 (13)° to the phenyl ring. The mol­ecular structure is stabilized by an intra­molecular O—H⋯O hydrogen bond...

Descripción
Sumario:The title compound, C(20)H(18)N(2)O(4), is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxy­phenyl ring mean plane, and by 1.19 (13)° to the phenyl ring. The mol­ecular structure is stabilized by an intra­molecular O—H⋯O hydrogen bond, making an almost planar (r.m.s. deviation = 0.0243 Å) six membered ring.
