A titanium-polyoxomolybdate K6(H3O)8[{PMo9O34TiO}2]·32H2O (1) was successfully synthesized and structurally characterized. It is an unprecedented instance that the titanium-containing polyoxomolybdate is water-soluble and was synthesized by using a conventional aqueous solution method. The Ti4+ ions exist in an unusual coordination mode. Besides, compound 1 as a wide band gap semiconductor showed evident photocatalytic activity for the oxidation of benzaldehyde into benzoic acid.
一种钛-聚钼酸盐 K6(H3O)8[{PMo9O34TiO}2]·32H2O（1）被成功合成并进行了结构表征。这是首例使用常规水溶液法合成的含钛聚钼酸盐具有水溶性的实例。Ti4+ 离子以一种不寻常的配位模式存在。此外，化合物 1 作为一种宽带隙半导体，在氧化苯甲醛生成苯甲酸的反应中表现出明显的光催化活性。
