摘要

在标题化合物 C14H14O4 中，香豆素环系统（r.m.s 偏差 = 0.016 Å）与五壬酸环之间的二面角为 36.26 (8)°。分子内的 C-H⋯O 短接触为 2.40 Å。Hirshfeld 表面分析表明，46.1% 的分子间相互作用来自 H⋯H 接触，28.6% 来自 H⋯O/O⋯H 接触，14.7% 来自 H⋯C/C⋯H 接触。

Synthesis, structure and Hirshfeld surface analysis of 2-oxo-2H-chromen-4-yl pentanoate

In the title compound, the dihedral angle between the coumarin ring system and the pentanoate ring is 36.26 (8)°. A short intramolecular C—H⋯O contact is observed.

In the title compound, C₁₄H₁₄O₄, the dihedral angle between the coumarin ring system (r.m.s deviation = 0.016 Å) and the pentanoate ring is 36.26 (8)°. A short intramolecular C—H⋯O contact of 2.40 Å is observed. Hirshfeld surface analysis reveals that 46.1% of the intermolecular interactions are from H⋯H contacts, 28.6% are from H⋯O/O⋯H contacts and 14.7% are from H⋯C/C⋯H.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
