title: 6-Fluoro-indan-1-one.
abstract: The title compound, C9H7FO, crystallizes with two independent mol-ecules in the asymmetric unit, in which corresponding bond lengths are the same within experimental error. The five-membered ring in each molecule is almost planar, with r.m.s. deviations of 0.016 and 0.029 Å. In the crystal, mol-ecules form sheets parallel to (1 0 0) via C-H⋯O and C-H⋯F inter-actions with F⋯F contacts [3.1788 (16) and 3.2490 (16) Å] between the sheets.
