By introducing the flexible 1,1'-(1,4-butanediyl)bis(imidazole) (bbi) ligand into the Keggin system, a novel multi-chain compound, (bbi)(1.5)[Cu(bbi)](4.5)[PW12O40](1.5) (1) was synthesized under the hydrothermal conditions. It was characterized by elemental and TG analysis, IR and XPS spectra, cyclic voltammetry, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. Compound 1 features in two sorts of polyoxometalates (POMs) chains, the poly-chain of [Cu(bbi)(14.5)[PW12O40] and the single-chain of (bbi)[PW2O40](0.5), induced by the POM clusters.
