Abstract

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) Å. 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.
