By combination of heteropolymolybdates and metal-Schiff-base complexes, two new organic-inorganic hybrid compounds {Mn(salen)(2)(H(2)O)(2)[AlMo(6)(OH)(6)O(18)]}[arg]·16H(2)O (1) and {Mn(salen)(2)(H(2)O)(2)[CrMo(6)(OH)(6)O(18)]}[arg]·11H(2)O (2) (salen = N,N'-ethylene-bis(salicylideneiminate) have been successfully isolated. Compounds 1 and 2 were structurally characterized by elemental analyses, IR spectra, thermogravimetric analysis, and single-crystal X-ray diffraction. To the best of our knowledge, compounds 1 and 2 represent the first single-crystal structures of metal-Schiff-base decorated polyoxometalates (POMs) compounds. Photocatalytic experiments indicated that both 1 and 2 exhibit high catalytic activity for photodegradation of RhB with UV irradiation. In addition, the magnetic properties of 1 were also investigated.
通过杂多酸盐和金属-Schiff 基配合物的组合，成功分离出两种新型有机-无机杂化化合物 {Mn(salen)(2)(H(2)O)(2)[AlMo(6)(OH)(6)O(18)]}[arg]·16H(2)O (1) 和 {Mn(salen)(2)(H(2)O)(2)[CrMo(6)(OH)(6)O(18)]}[arg]·11H(2)O (2) (salen = N,N'-ethylene-bis(salicylideneiminate))。化合物 1 和 2 的结构通过元素分析、红外光谱、热重分析和单晶 X 射线衍射进行了表征。据我们所知，化合物 1 和 2 代表了首例金属-Schiff 基修饰的多金属氧酸盐（POMs）化合物的单晶结构。光催化实验表明，化合物 1 和 2 在紫外光照射下均表现出对 RhB 的高效光降解催化活性。此外，还研究了化合物 1 的磁性。
