چکیده
In the title compound, C(21)H(24)O(3), the enone unit is in the s-cis configuration. The dihedral angle between the benzene rings is 2.18 (4)°. In the crystal, mol-ecules are linked by pairs of O-H⋯O inter-molecular hydrogen bonds, forming inversion dimers. The crystal structure is also consolidated by C-H⋯π inter-actions.

In the title compound, C(25)H(32)O(3), the asymmetric unit contains two crystallographically independent mol-ecules: both enone groups adopt an s-cis configuration. In the crystal, O-H⋯O and C-H⋯O inter-molecular inter-actions form bifurcated hydrogen bonds, which generate R(1) (2)(6) ring motifs. These inter-molecular inter-actions link the mol-ecules into one-dimensional chains along the [10]...
