摘要：

The crystal structures of three polymorphic forms of ethyl maltol (2-ethyl-3-hydroxy-4-pyranone), C7H8O3, have been determined. The polymorphs exhibit different molecular arrangements through intermolecular hydrogen bonding. Form (1) contains nearly planar chains of molecules, (2) contains three-dimensional or spiral chains and (3) contains hydrogen-bonded dimers.
