Abstract Two [TeMo6O24]6−-based metal-organic complexes {Co4(Htyptz-I)2[TeMo6O24](H2O)12}·4H2O (1), {Co3(H2typtz-II)2[TeMo6O24](H2O)8}·6H2O (2) (H2typtz-I = 3-(tetrazol-5-yl)-5-(pyrid-2-yl)-1,2,4-triazole, H2typtz-II = 3-(tetrazol-5-yl)-5-(pyrid-4-yl)-1,2,4-triazole) have been synthesized by the hydrothermal method. Complex 1 shows a 2D polymeric layer based on the μ3-bridging H2typtz-I and the μ4-bridging TeMo6 anions, furthermore the 2D layers are extended into a 3D architecture through the weak hydrogen bonds. When H2typtz-II was used, complex 2 form a different 2D polymeric layer based on the μ2-bridging H2typtz-II and the μ2-bridging TeMo6 anions. It is worth noting that the difference between H2typtz-I and H2typtz-II is only the different N site on pyridine. The photocatalytic properties, electrochemical behaviors and electrocatalytic activities of two [TeMo6O24]6−-based complexes have been investigated in detail.

摘要 两种[TeMo6O24]6-基金属有机配合物{Co4(Htyptz-I)2[TeMo6O24](H2O)12}·4H2O(1),{Co3(H2typtz-II)2[TeMo6O24](H2O)8 }·6H2O (2) (H2typtz-I = 3-(tetrazol-5-yl)-5-(pyrid-2-yl)-1,2,4-triazole, H2typtz-II = 3-(tetrazol-5- yl)-5-(pyrid-4-yl)-1,2,4-三唑)已通过水热法合成。复合物 1 显示了基于 μ3 桥接 H2typtz-I 和 μ4 桥接 TeMo6 阴离子的 2D 聚合物层，此外，2D 层通过弱氢键扩展为 3D 结构。当使用 H2typtz-II 时，复合物 2 基于 μ2-桥接 H2typtz-II 和 μ2-桥接 TeMo6 阴离子形成不同的二维聚合物层。值得注意的是，H2typtz-I和H2typtz-II的区别仅在于吡啶上的N位不同。光催化性能，
