Popis:	The structure of demethylchodatin, a xanthone from the lichen Lecanora pachysoma, has been established by X-ray analysis of the corresponding triacetate derivative. Crystals of demethylchodatin triacetate are monoclinic, P 21/a, a 10.120(3), b 11.278(3), c 19.173(4) Ǻ, β 94.68(3)°; Z 4. Refinement of 1411 data with I > 3σ(I) gave conventional R factors of 0.041 and 0.033.
