4-Hy-droxy-methyl-10-meth-oxy-17,22-dioxapenta-cyclo-[21.2.2.2(13,16).1(3,7).0(11,30)]triaconta-1(25),3,5,7(30),8,10,13,15,23,26,28-undeca-ene-2,12-dione acetone monosolvate.
In the title compound, C(30)H(26)O(6)·C(3)H(6)O, the syn-oriented benzoyl groups are nearly parallel to each other; the dihedral angle between their benzene rings is 15.9 (1)°. They form dihedral angles of 72.5 (1) and 84.3 (1)° with the naphthalene system. In the crystal, mol-ecules are linked into a three-dimensional architecture by C-H⋯O and C-H⋯π inter-actions.
