Abstract

Three new organic–inorganic hybrid compounds based on PMo12O40n (n = 3 or 4) polyanions and CuI–pz/CuI–pz–Cl porous coordination polymers: [CuI(pz)]3[PMoVI12O40] (1), [CuI(pz)1.5]4[PMoVMoVI11O40]·pz·2H2O (2), [CuI3(pz)3Cl][CuI2(pz)3(H2O)][PMoVMoVI11O40] (3) (pz = pyrazine) have been hydrothermally prepared and characterized by elemental analysis, IR, TG, XRD, XPS and single-crystal X-ray diffraction. Compound 1 presents a three-dimensional CuI–pz framework with cube-like chambers, into which PMoVI12O403− Keggin ions are incorporated. Compound 2 shows a three-dimensional sandwich-like framework, and PMoVMoVI11O404− polyanions are located in the octagonal voids of every two-dimensional CuI–pz 4182 network structure. Compound 3 exhibits a two-dimensional Cl-bridged CuI–pz–Cl double-layer structure, and two kinds of PMoVMoVI11O404− polyanions as bridging linkers connect two adjacent double-layers to form a three-dimensional organic–inorganic framework through CuI–O bonds. Additionally, their electrochemical characters, electrocatalytic behaviors and solid state fluorescent properties at room temperature have been investigated in detail.
