Both structures were successfully solved and refined. The packing of identical layers of molecules is different for monoclinic and orthorhombic forms.Crystal structure of 5-oxatricyclo[5.1.0.0(1,3)]octane-4-one: two polymorphs in one crystaljournal_article10.1107/S010876810200887X12149557000177124200013
