Abstract
5,13-Epoxy-3β-hydroxy-lactara-2(9),5,7(13)-trien-4,8-dion was investigated by X-ray diffractometric methods. The compound is orthorhombic:P212121,a=7.677(1),b=11.244(2),c=15.277(2) Å andZ=4. The structure was solved by direct methods and refined by full-matrix least-squares, givingR=0.0387 for 1522 observed reflections. An internal hydrogen bond of medium strength was registered in the molecular structure.
