Four titanium-oxo-clusters with cyclohex-3-ene-1-carboxylate (Cec) ligands, Ti(μ-O)(μ-O)(Cec)(OPr) (PTC-91; HOPr = isopropanol), Ti(μ-O)(Cec)(OPr) (PTC-92 and PTC-93) and H[Ti(μ-O)(μ-O)(Cec)(OPr)] (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 Ti clusters with different conformations are presented in PTC-91, PTC-92 and PTC-93, while PTC-94 is an unusual Ti cluster. The photocatalytic studies reveal that PTC-91 and PTC-94 have good H evolution ability.
分别在不同条件下通过溶剂热法合成了四种带有环己-3-烯-1-羧酸酯（Cec）配体的钛氧簇，即Ti(μ-O)(μ-O)(Cec)(OPr)（PTC-91；HOPr = 异丙醇）、Ti(μ-O)(Cec)(OPr)（PTC-92和PTC-93）以及H[Ti(μ-O)(μ-O)(Cec)(OPr)]（PTC-94）。这些带有相同Cec配体的簇具有完全不同的结构，并且它们在水和其他常见溶剂中稳定。PTC-91、PTC-92和PTC-93中呈现出具有不同构象的钛簇，而PTC-94是一种不寻常的钛簇。光催化研究表明PTC-91和PTC-94具有良好的析氢能力。
