In this paper, three pure inorganic eight-connected self-catenated networks based on the Silverton-type polyoxometalate [CeMo(12)O(42)](8) with lanthanide, transition metal and alkali metal cations as linkers: [Li(H(2)O)(4)](2)Co(H(2)O)(4)Ce(H(2)O)(3)[CeMo(12)O(42)]center dot 3H(2)O (1), H(0.5)[Li(H(2)O)(4)](2.5)[Ni(H(2)O)(4)](0.5)Ce(H(2)O)(3)[CeMo(12)O(42)]center dot 3H(2)O (2) and H[Li(H(2)O)(4)](3)Ce(H(2)O)(3)[CeMo(12)O(42)]center dot 3H(2)O (3) have been successfully synthesized and characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, X-ray photoelectron spectroscopy, electrochemical analyses and single crystal X-ray diffraction, The single crystal X-ray diffraction analyses reveal that compounds 1-3 are isostructural. The [Ce(IV)Mo(12)O(42)](8) polyoxoanions are connected by Ce(4 ) to form the infinite I D chains. And then the parallel stacking chains linked by transition metal cations and lithium ions construct to an eight-connected self-catenated 4(24)56(3) topology framework.
