title: Two crystalline modifications of 2-hydroxycyclopent-2-enone
abstract: The orthorhombic form of 2-hydroxycyclopent-2-enone, C(5)H(6)O(2), consists of chains of hydrogen-bonded molecules aligned along a twofold screw axis. The monoclinic form contains two independent molecules, which have different orientations of the hydroxyl proton, and which assemble into ribbons along a twofold screw axis.
