Coumarin-3-carboxylic acid.
In the structure of the title compound, C10H6O4, there is a single intramolecular hydrogen bond. In addition, there are a number of significant intermolecular C-H...O attractive interactions. These interactions account in part for the rather high density for an ordinary monocarboxylic acid, 1.522 Mg m(-3).
