Description
Summary:The molecular structure of the title compound, C18H16O3, 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 methoxy groups and the indanone ring are −14.67 (11) and −1.11 (12)°. In the crystal, molecules are connected into a ribbon along the a axis via weak intermolecular C—H...O hydrogen bonds. Weak intermolecular C—H...π and π–π [centroid–centroid distance = 3.7086 (6) Å] interactions are also observed.
