2,2-[(E)-3,3-Diphenylprop-2-ene-1,1-diyl]bis(3-hydroxycyclohex-2-en-1-on e)

Abstract

In the title compound, C27H26O4, each of the cyclohexenone rings adopts a half-chair conformation. The dihedral angle between the two phenyl rings is 89.53 (5)degrees. The hydroxy and carbonyl O atoms face each other and are orientated to allow the formation of two intramolecular O-H center dot center dot center dot O hydrogen bonds, which are typical of xanthene derivatives.
