The crystal structure of 9–(1,1‐dimethyl–2‐propenyl)‐4‐hydroxy‐7H‐Furo‐[3,2‐g]‐benzopyran‐7‐one has been determined from X‐ray diffraction data. The compound crystallizes in the monoclinic space group C2/c with unit cell parameters a = 8.976(3) Å, b = 16.621(2) Å, c = 17.818(2) Å, β = 95.79(2) Å. The gross structure was determined by direct methods and refined to a final value of R = 0.053. The three ring framework of the molecule is nearly planar. The side chain attached at the atomic position C(9) possesses significant foldings and has been found inclined to the ring system of the molecule.
