In this paper, three pure inorganic eight-connected self-catenated networks based on the Silverton-type polyoxometalate [CeMo{sub 12}O{sub 42}]{sup 8-} with lanthanide, transition metal and alkali metal cations as linkers: [Li(H{sub 2}O){sub 4}]{sub 2}Co(H{sub 2}O){sub 4}Ce(H{sub 2}O){sub 3}[CeMo{sub 12}O{sub 42}].3H{sub 2}O (1), H{sub 0.5}[Li(H{sub 2}O){sub 4}]{sub 2.5}[Ni(H{sub 2}O){sub 4}]{sub 0.5}Ce(H{sub 2}O){sub 3}[CeMo{sub 12}O{sub 42}].3H{sub 2}O (2) and H[Li(H{sub 2}O){sub 4}]{sub 3}Ce(H{sub 2}O){sub 3}[CeMo{sub 12}O{sub 42}].3H{sub 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{sup IV}Mo{sub 12}O{sub 42}]{sup 8-} polyoxoanions are connected by Ce{sup 4+} to form the infinite 1D chains. And then the parallel stacking chains linked by transition metal cations and lithium ions construct to an eight-connected self-catenated 4{sup 24}56{sup 3} topology framework. - Graphical Abstract: Three extended frameworks based on Silverton-type polyoxometalate have been successfully synthesized. In these compounds, [Ce{sup IV}Mo{sub 12}O{sub 42}]{sup 8-} clusters are connected by lanthanide, transition metal and Li{sup +} to form a 4{sup 24}56{sup 3} network.
