The molecule of the title compound, C 28 H 22 O 2 , is centrosym- metric with the inversion centre located at the mid-point of the C C bond [1.178 (5) A ˚ ]. The hydroxyl groups therefore lie on either side of the molecule. The crystal structure is stabilized by O—HO hydrogen bonds, leading to the formation of a linear supramolecular chain along the b axis. Related literature For related structures, see: Braga et al.
