Abstract
The crystal structures of three polymorphic forms of ethyl maltol (2-e thyl-3-hydroxy-4-pyranone), C7H8O3, have been determined. The polymorp hs exhibit different molecular arrangements through intermolecular hyd rogen bonding. Form (1) contains nearly planar chains of molecules, (2 ) contains three-dimensional or spiral chains and (3) contains hydroge n-bonded dimers.
