organic compounds
The title compound, C29H22O3, was prepared from oxidation of tetraphenylcyclopentadienone with tetranitromethane. The cyclopentenone ring has a C5-envelope conformation with an elongated Csp3—Csp3 bond length of 1.569 (2) Å. One hydroxyl group takes part in a bifurcated hydrogen bond involving an intra- and intermolecular bond to adjacent hydroxyl groups, O
O 2.6299 (16) and 2.9279 (15) Å], while the second forms an intermolecular hydrogen bond to an adjacent carbonyl O atom [OO 2.8441 (18) Å].
