摘要：

The crystal structure of angenomalin (8,9-dihydro-8-(1-methylethenyl)-2 H-furo[2,3-h]-1-benzopyran-2-one) was determined by X-ray structure analysis. It crystallizes in the orthorhombic space group P2(1)2(1)2(1) with cell parameters a = 5.210(1), b = 10.407(1), c = 20.478(2) angstrom. The structure was solved by direct methods and refined to R = 0.037. The coumarin moiety is planar and the crystal structure is stabilized by van der Waals interactions.
