Low-temperature and high-pressure polymorphs of isopropyl alcohol†
Abstract
Single-crystal X-ray diffraction has been used to elucidate the structure of two polymorphs of isopropyl alcohol, one grown through in situ cryo-crystallisation, the other through high-pressure crystallisation. The packing in both structures is dominated by O–H⋯O hydrogen bonds, with the high-pressure polymorph being significantly more dense than the low-temperature structure.
