摘要：

In the title molecule, C11H10ClFO2, the benzene ring, the F atom and the O atom of the dihydropyran ring are essentially coplanar, with an r.m.s. deviation of 0.007 angstrom. The dihydropyran ring is in a half-chair conformation. In the crystal, molecules are linked by pairs of weak C-H center dot center dot center dot pi hydrogen bonds, forming inversion dimers.
