Five new inorganic–organic hybrid compounds, [Co2(HDIBA)2(DIBA)2(H2O)4]·HPW12O40·2H2O (1), [Ni2(HDIBA)2(DIBA)2(H2O)4]·HPW12O40 (2), [Ag(H2DIBA)2·PW12O40]·2H2O (3), [Ag(H2DIBA)2·PMo12O40]·2H2O (4) and [Ag(H2DIBA)2·HSiMo12O40]·2H2O (5) (HDIBA = 3,5-di(1H-imidazol-1-yl)benzoic acid), based on Keggin-type polyoxometalates (POMs) have been synthesized by a hydrothermal method. Their structures were characterized through single-crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, IR spectroscopy and thermogravimetric analysis. The discrete units of 1 are further extended into a 3D supramolecular structure by π–π stacking and hydrogen bonding interactions. In compound 2, wavy ladderlike bimetallic chains are linked by hydrogen bonding interactions to form a 3D supramolecular structure, with POMs filling in the cages. In compounds 3–5, POMs act as bidentate inorganic bridging ligands to link [Ag(H2DIBA)2]3+ into 1D chains. Their cyclic voltammetric behaviors and electrocatalytic properties were studied. Notably, compound 4 exhibits amperometric sensing performance toward BrO3−. The organic dye pollutant removal behaviors of 1–5 were explored. In addition, the antibacterial/antifungal activities and photoluminescence properties of 3–5 were also investigated.

基于 Keggin 型多金属氧酸盐和 3,5-二（1H-咪唑-1-基）苯甲酸配体的五种新型多功能无机-有机杂化物
五种新的无机-有机杂化化合物，[Co 2 (HDIBA) 2 (DIBA) 2 (H 2 O) 4 ]·HPW 12 O 40 ·2H 2 O ( 1 ), [Ni 2 (HDIBA) 2 (DIBA) 2 (H 2 O) 4 ]·HPW 12 O 40 ( 2 ), [Ag(H 2 DIBA) 2 ·PW 12 O 40 ]·2H 2 O ( 3 ), [Ag(H 2 DIBA) 2 ·PMo 12O 40 ]·2H 2 O ( 4 ) 和[Ag(H 2 DIBA) 2 ·HSiMo 12 O 40 ]·2H 2 O ( 5 ) (HDIBA = 3,5-di(1 H -imidazol -1-yl)苯甲酸），基于 Keggin 型多金属氧酸盐（POMs），已通过水热法合成。通过单晶X射线衍射、元素分析、粉末X射线衍射、红外光谱和热重分析对其结构进行了表征。1的离散单元通过 π-π 堆叠和氢键相互作用进一步扩展为 3D 超分子结构。在化合物2，波状梯状双金属链通过氢键相互作用连接形成 3D 超分子结构，POM 填充在笼中。在化合物3–5中，POM 作为双齿无机桥接配体将 [Ag(H 2 DIBA) 2 ] 3+连接成一维链。研究了它们的循环伏安行为和电催化性能。值得注意的是，化合物4对 BrO 3 -表现出安培传感性能。探索了1-5的有机染料污染物去除行为。此外，还研究了3-5的抗菌/抗真菌活性和光致发光特性。
