title: 2-[(E)-2,5-Dimethoxy-benzyl-idene]indan-1-one.
abstract: In the title compound, C(18)H(16)O(3), the mean plane of the nine-membered indane system makes a dihedral angle of 3.71 (17)° with the benzene ring of the dimethoxy-phenyl group. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen contacts. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link neighbouring mol-ecules into one-dimensional extended chains along the [100] direction. In the structure, C-H⋯π inter-actions are also observed.
