Abstract
Ethyl 2-[(2-oxo-2H-chromen-6-yl)oxy]acetate, a coumarin derivative, crystallizes in sheets, within which molecules are held by weak C—H⋯O hydrogen-bonding interactions and between which molecules interact by π–π stacking and additional C—H⋯O weak hydrogen bonds between ethyl acetoxy groups.
Ethyl 2-[(2-oxo-2H-chromen-6-yl)oxy]acetate, C13H12O5, a member of the pharmacologically important class of coumarins, crystallizes in the monoclinic C2/c space group in the form of sheets, within which molecules are related by inversion centers and 21 axes. Multiple C—H⋯O weak hydrogen-bonding interactions reinforce this pattern. The planes of these sheets are oriented in the approximate direction of the ac face diagonal. Intersheet interactions are a combination of coumarin system π–π stacking and additional C—H⋯O weak hydrogen bonds between ethyl acetoxy groups.
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.
