2-[(E)-2,5-Dimethoxybenzylidene]indan-1-one

Abstract

In the title compound, C18H16O3, the mean plane of the nine-membered indane system makes a dihedral angle of 3.71 (17)° with the benzene ring of the dimethoxyphenyl group. The molecular conformation is stabilized by intramolecular C—H...O hydrogen contacts. The crystal structure is stabilized by intermolecular C—H...O interactions, which link neighbouring molecules into one-dimensional extended chains along the [100] direction. In the structure, C—H...π interactions are also observed.
