title: Synthesis and photocatalytic H2evolution properties of four titanium-oxo-clusters based on a cyclohex-3-ene-1-carboxylate ligand.
abstract: Four titanium-oxo-clusters with cyclohex-3-ene-1-carboxylate (Cec) ligands, Ti6(μ2-O)2(μ3-O)2(Cec)4(OiPr)12(PTC-91; HOiPr = isopropanol), Ti6(μ3-O)6(Cec)6(OiPr)6(PTC-92 and PTC-93) and H2[Ti18(μ2-O)11(μ3-O)14(Cec)20(OiPr)4] (PTC-94), have been solvothermally synthesized under different conditions, respectively. These clusters with the same Cec ligand show totally different structures, and they are stable in water and other common solvents. The Ti6clusters with different conformations are presented in PTC-91, PTC-92 and PTC-93, while PTC-94 is an unusual Ti18cluster. The photocatalytic studies reveal that PTC-91 and PTC-94 have good H2evolution ability.
