✦ Synopsis

The coordination of [Ti(hfaa)~2~Cl~2~] (hfaa = hexafluoroacetylacetonate) with the hydroxyl-containing bidentate ligand 2,2′-biphenol yielded the title compound, [{Ti(hfaa)~2~}~2~(μ-2,2′-biphenolato)(μ-oxo)] or [Ti~2~(C~5~HF~6~O~2~)~4~(C~12~H~8~O~2~)O]. The molecule has crystallographic twofold rotation symmetry. The biphenolate ligand bridges the two Ti atoms.
