Abstract

In the title mol-ecule, C11H10O3, the fused dihydro-pyran ring is in a half-chair conformation with the O atom and the methyl-ene C atom positioned 0.1318 (13) and 0.143 (2) Å, respectively, on either side of the mean plane formed by the other four atoms. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules along [001].

摘要

在标题分子C₁₁H₁₀O₃中，稠合的二氢吡喃环呈半椅式构象，O原子和亚甲基C原子分别位于由其他四个原子形成的平均平面两侧0.1318 (13) Å和0.143 (2) Å处。在晶体中，弱C—H⋯O氢键沿[001]方向连接分子。
