2,2-[(E)-3,3-Diphenyl-prop-2-ene-1,1-di-yl]bis-(3-hy-droxy-cyclo-hex-2-en-1-one).
In the title compound, C(27)H(26)O(4), each of the cyclo-hexenone rings adopts a half-chair conformation. The dihedral angle between the two phenyl rings is 89.53 (5)°. The hy-droxy and carbonyl O atoms face each other and are orientated to allow the formation of two intra-molecular O-H⋯O hydrogen bonds, which are typical of xanthene derivatives.
