MOLECULAR AND CRYSTAL STRUCTURE OF 4,4,4-TRIFLUORO-3,3-DIHYDROXY-1-THIOPHENE-2-YL-BUTANE-1-ONE
An X-ray diffraction analysis and quantum chemical calculations of hydrated 2-thenoyltrifluoroacetone show that the planar diketone, form of ТТА found in its metal complexes, does not occur in the free ligand. Hydrated ТТА with two geminal hydroxo groups has a non-planar structure stabilized by an intramolecular hydrogen bond.
