9-(4-Chloro-phen-yl)-4a-hy-droxy-4,4a,5,6,9,9a-hexa-hydro-3H-xanthene-1,8(2H,7H)-dione.

ABSTRACT: In the title compound, C(19)H(19)ClO(4), the central fused ring and the attached cyclo-hexene ring adopt envelope conformations, while the cyclo-hexane ring adopts a chair conformation. The crystal packing is stabilized by O-H⋯O hydrogen bonds, which link the mol-ecules into a chain along the b axis. Weak C-H⋯O bonds also occur.
