title: 2,2'-[(1E)-3-Phenyl-prop-2-ene-1,1-di-yl]bis-(3-hy-droxy-5,5-dimethyl-cyclo-hex-2-en-1-one).
abstract: In the title mol-ecule, C(25)H(30)O(4), the two cyclo-hexene rings adopt envelope conformations. The two hy-droxy groups are involved in the formation of intra-molecular O-H⋯O hydrogen bonds. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules related by translation along the axis a into chains.
