The title compound, C(21)H(16)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The pyrazole ring and one of the hydr-oxy-substituted benzene rings are approximately coplanar, forming a dihedral angle of 7.5 (3)°. The relative conformation of these rings may be influenced by an intra-molecular O-H⋯N hydrogen bond. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds involving different hydr-oxy groups of symmetry-related mol-ecules form extended chains along [201].
标题化合物C(21)H(16)N(2)O(2)由1-(2-羟基苯基)-3-(4-甲氧基苯基)丙烷-1,3-二酮衍生而来。吡唑环和其中一个羟基取代的苯环近似共面，形成7.5 (3)°的二面角。这些环的相对构象可能受分子内O-H⋯N氢键影响。在晶体结构中，涉及对称相关分子不同羟基的分子间O-H⋯O氢键沿[201]方向形成延伸链。
