title: 4-Bromo-2-(4-fluoro-benzyl-idene)indan-1-one.
abstract: In the mol-ecule of the title compound, C(16)H(10)BrFO, the indane ring system is planar with a maximum deviation of 0.020 (3) Å. An intra-molecular C-H⋯O inter-action results in the formation of a planar ring, which is oriented at dihedral angles of 2.24 (3) and 2.34 (3)° with respect to the adjacent rings. π-π contacts between the benzene and indane rings [centroid-centroid distances = 3.699 (1) and 3.786 (1)Å] may stabilize the crystal structure.
