Syntheses, structures and photoelectrochemical properties of phosphite-stabilized titanium-oxo clusters containing 2,2′-biphenolato ligands

The solvothermal reaction of Ti(OiPr)4, phosphorous acid and 2,2′-biphenol under different conditions offer three titanium-oxo clusters with the {Ti4P2}, {Ti8P4} and {Ti8P2} core structures, respectively.75
