Abstract: The title compound, C₁₇H₂₂O₃, which was synthesized by the condensation of cyclohexane-1,3-dione and n-valeraldehyde, includes a partially hydrogenated xanthene ring system. The molecule has crystallographic mirror symmetry. The central ring adopts a very shallow boat conformation while the symmetry-related outer six-membered rings have sofa conformations. Molecules form extended tapes in the c-axis direction though weak C-HO interactions.
