The title compound, C(14)H(17)FO(2), was obtained from anti-4a,9a:8a,10a-diep-oxy-1,4,4a,5,8,8a,9,9a,10,10a-deca-hydro-anthra-cene via tandem hydrogen-fluoride-mediated epoxide ring-opening and transannular oxacyclization. With the two cyclo-hexene rings folded towards the oxygen bridge, the title tetra-cyclic fluoro-alcohol mol-ecule displays a conformation remin-iscent of a pagoda. The crystal packing is effected via inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into a zigzag chain along the b axis.
