bidentate bridging ligand with one tetrazolyl group. In 2, the 3-bptzb acts as a tetradentate bridging ligand with the tetrazolyl and pyridyl groups linking AgI ions to generate a 3D metal–organic framework (MOF), which contains charming meso-helix chains. The Keggin anions acting as bidentate inorganic ligands reside in the distorted tetragonal channels of the MOF. In compound 3, the 3-bptzb adopts versatile
通过将前所未有的灵活的双(吡啶基-四唑)异构体引入多金属氧酸盐(POM)系统中,三种基于POM的化合物Ag 2(4-bptzb)2(H 2 O)2 [H 2 PMo 12 O 40 ] 2 }·4-bptzb·5H 2 O(1),[Ag 4(3-bptzb)2(PMo V Mo VI 11 O 40)]·2H 2 O(2)和Ag 3(3-bptzb)2.5(H 2 O)2 [H 3P 2 W 18 O 62 ](3)[4-bptzb = 1,4-双(5-(4-吡啶基)四唑基)丁烷和3-bptzb = 1,4-双(5-(3-吡啶基)四唑基丁烷],是在水热条件下合成的,并通过单晶X射线衍射分析对其结构进行了表征。化合物1表现出由两个Keggin [PMo 12 O 40 ] 3–阴离子和双核[Ag 2(trans -4-bptzb)2 ] 2+亚基构成的二聚结构,其中trans -4-bpt
