The mol-ecular structure of the title compound, C(18)H(16)O(3), is roughly planar; the maximum deviation of the indanone ring system is 0.027 (1) Å and it makes a dihedral angle of 2.69 (3)° with the phenyl ring. The torsion angles between the two meth-oxy groups and the -indanone ring are -14.67 (11) and -1.11 (12)°. In the crystal, mol-ecules are connected into a ribbon along the a axis via weak inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π and π-π [centroid-centroid distance = 3.7086 (6) Å] inter-actions are also observed.
标题化合物C(18)H(16)O(3)的分子结构大致呈平面状;茚满酮环系的最大偏差为0.027 (1) Å,它与苯环的二面角为2.69 (3)°。两个甲氧基与茚满酮环之间的扭转角分别为 -14.67 (11)° 和 -1.11 (12)°。在晶体中,分子通过弱分子间C-H⋯O氢键沿a轴连接成一条链。还观察到弱分子间C-H⋯π和π-π [质心-质心距离 = 3.7086 (6) Å] 相互作用。
