基于octamolybdates一系列无机混合材料,银离子,和多齿的N-donor配体,即[Ag)(2)(2、3 ' -tmbpt)(β- Mo (8) O (26)) (0.5)] (1), (Ag)(2)(2、4 ' -tmbpt)(2)(α- Mo (8) O (26)) (0.5) (H (2) O)(0.5)]·2 H (2) O (2), (Ag)(3)(3、3’-tmbpt)(2)(α- H(2)莫(8)O(26))(0.5)(β- Mo (8) O(26)) 3.5(0.5)]·H (2) O (3), (Ag)(2)(3、3’-tmbpt)(ε- Mo (8) O(26)) 1.75(0.5)]·H (2) O (4), (Ag)(2)(3、4 ' -tmbpt)(2)(β- Mo (8) O(26)) 0.5(0.5)]·H (2) O(5)和(Ag)(3、4 ' -Htmbpt)(β- Mo (8) O (26)) (0.5) (6),在2、3 ' -tmbpt = 1 - ((1 h - 2 4-triazol-1-yl)甲基)3 - (3-pyridyl) 5 - (2-pyridyl) 1、2,4-triazole), 2、4 ' -tmbpt = 1 - ((1 h - 2 4-triazol-1-yl)甲基)3 - 5 (4-pyridyl) - (2-pyridyl) 1, 2, 4-triazole), 3、3”-tmbpt = 1 - ((1 h - 2 4-triazol-1-yl)甲基)3,5-bis (3-pyridyl) 1、2,4-triazole,和3,4 ' -tmbpt = 1 - ((1 h - 2 4-triazol-1-yl)甲基)3 - 5 (4-pyridyl) - (3-pyridyl) 1, 2, 4-triazole)在水热条件下合成。化合物1呈现罕见的（4·8(2)）（4(2)）(4(2)·8(4))(4（3)·8（20）·10(5)）拓扑结构的3D（3,4,8）连接网络。化合物2具有(6(4)·8(2))(4(2)·6(3)·8(2))(4(2)·6(8)·8(2))(4(2)·6（8)·8(4)·10）拓扑结构，是一种罕见的3D（4,6）连接自链骨架。化合物3是基于两种不同的[Mo(8)O(26)]（4-）异构体的稀有三维骨架。化合物4是由银有机薄片和稀有的[ε-Mo(8)O(26)]（4-）阴离子构成的三维骨架。化合物5呈现出有趣的1D→2D多线程结构。化合物6为二维层状结构，并通过N-H···O氢键连接形成三维超分子结构。通过红外光谱（IR）、元素分析、粉末x射线衍射（PXRD）、电化学和光致发光等手段对其结构进行了进一步表征。此外，还研究了化合物3 ~ 6的光催化降解有机污染物的活性。
Series of inorganic-organic hybrid materials based on octamolybdates, silver ions, and multidentate N-donor ligands, namely, [Ag(2)(2,3'-tmbpt)(β-Mo(8)O(26))(0.5)] (1), [Ag(2)(2,4'-tmbpt)(2)(α-Mo(8)O(26))(0.5)(H(2)O)(0.5)]·2H(2)O (2), [Ag(3)(3,3'-tmbpt)(2)(α-H(2)Mo(8)O(26))(0.5)(β-Mo(8)O(26))(0.5)]·3.5H(2)O (3), [Ag(2)(3,3'-tmbpt)(ε-Mo(8)O(26))(0.5)]·1.75H(2)O (4), [Ag(2)(3,4'-tmbpt)(2)(β-Mo(8)O(26))(0.5)]·0.5H(2)O (5), and [Ag(3,4'-Htmbpt)(β-Mo(8)O(26))(0.5)] (6), where 2,3'-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3-(3-pyridyl)-5-(2-pyridyl)-1,2,4-triazole), 2,4'-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3-(4-pyridyl)-5-(2-pyridyl)-1,2,4-triazole), 3,3'-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(3-pyridyl)-1,2,4-triazole, and 3,4'-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3-(4-pyridyl)-5-(3-pyridyl)-1,2,4-triazole) have been synthesized under hydrothermal conditions. Compound 1 displays a rare 3D (3,4,8)-connected net with (4·8(2))(4(2)·8(4))(4(3)·8(20)·10(5)) topology. Compound 2 shows a rare 3D (4,6)-connected self-catenated framework with (6(4)·8(2))(4(2)·6(3)·8(2))(4(2)·6(8)·8(4)·10) topology. Compound 3 is a scarce 3D framework based on two different kinds of [Mo(8)O(26)](4-) isomers. Compound 4 exhibits a 3D framework constructed by silver-organic sheets and the rare [ε-Mo(8)O(26)](4-) anions. Compound 5 shows an interesting 1D → 2D polythreaded structure. Compound 6 displays a 2D layer structure, which is further linked by the N-H···O hydrogen bonds to form a 3D supramolecular architecture. Their structures have been further characterized by infrared spectra (IR), elemental analyses, powder X-ray diffraction (PXRD), electrochemistry and photoluminesce. Moreover, the photocatalytic activities for degradation of organic pollutant have been investigated for compounds 3-6.
