Molecular arrangement planarization induces a high-pressure polymorphism transition of the hydrogen-bonded organic crystal maltol.

The high-pressure behavior of maltol (3-hydroxy-2-methyl-4H-pyran-4-one, C6H6O3) molecular crystals has been investigated using in situ high-pressure Raman spectroscopy and synchrotron angular dispersive x-ray diffraction. The results of the high-pre…
