Popis: The title compound, C 13 H 15 O 7 P, consists of two condensed rings, namely, a pyranoid ring with an axially attached partially disordered dimethoxyphosphoryl group and a benzene ring. The conformation of the pyranoid ring is halfway between half-boat and half-chair, and the fusion of the rings does not exert significant influence on the planarity of the benzene ring.
