Abstract
In the title mol-ecule, C11H10ClFO2, the benzene ring, the F atom and the O atom of the di-hydro-pyran ring are essentially coplanar, with an r.m.s. deviation of 0.007 Å. The di-hydro-pyran ring is in a half-chair conformation. In the crystal, mol-ecules are linked by pairs of weak C-H⋯π hydrogen bonds, forming inversion dimers.
摘要
在标题分子C₁₁H₁₀ClFO₂中，苯环、F原子和二氢吡喃环的O原子基本共面，均方根偏差为0.007 Å。二氢吡喃环呈半椅式构象。在晶体中，分子通过成对的弱C-H⋯π氢键相连，形成反演二聚体。
