In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16)°. In the crystal, the mol-ecules are packed in an anti-parallel fashion in layers along the a axis. In each layer, very weak C-H⋯O hydrogen bonds occur between the meth-oxy and methyl ester groups. Weak C-H⋯π inter-actions between the 4'- and 5'-meth-oxy groups and neighbouring benzene rings [meth-oxy-C-ring centroid distances = 4.075 and 3.486 Å, respectively] connect the layers.
在标题化合物C₁₇H₁₈O₅中，苯环之间的二面角为31.23 (16)°。在晶体中，分子沿a轴以反平行方式堆积成层。在每层中，甲氧基和甲酯基团之间存在非常弱的C-H⋯O氢键。4'-和5'-甲氧基与相邻苯环之间的弱C-H⋯π相互作用[甲氧基-C-环质心距离分别为4.075和3.486 Å]连接各层。
