(E)-2,2′-[3-(4-Fluorophenyl)prop-2-ene-1,1-diyl]bis(3-hydroxy-5, 5-dimethylcyclohex-2-en-1-one)

Abstract

In the title compound, C25H29FO4, each cyclohexenone ring has an envelope conformation with the dimethyl-substituted atom as the flap. The hydroxy and carbonyl groups form two intramolecular O - H？O hydrogen bonds, as is typical for xanthene derivatives. In the crystal, very weak C - H？O hydrogen bonds link molecules into dimers. ？ 2013 Cha et al.
