In the mol-ecular structure of the title compound, C(15)H(15)NO(3), the two benzene rings are twisted with respect to each other, making a dihedral angle of 75.11 (10)°. In the amide fragment, the C=O and C-N bond distances are 1.248 (3) and 1.321 (3) Å, respectively, indicating electron delocalization. A partially ovelapped arrangement between parallel hydroxy-methoxy-benzene rings is observed in the crystal structure, and the face-to-face distance of 3.531 (16) Å suggests the existence of weak π-π stacking. N-H⋯O and O-H⋯O hydrogen bonding is also present in the crystal structure.
在标题化合物C(15)H(15)NO(3)的分子结构中,两个苯环相互扭曲,二面角为75.11 (10)°。在酰胺片段中,C=O和C-N键长分别为1.248 (3) Å和1.321 (3) Å,表明存在电子离域。在晶体结构中观察到平行的羟基甲氧基苯环之间存在部分重叠排列,面对面距离为3.531 (16) Å,表明存在弱π-π堆积。晶体结构中还存在N-H⋯O和O-H⋯O氢键。
