In this work, two rare high-dimensional polyoxoniobates with formulas of H-9[Cu(en)(H2O)(2)][Cu(en)(2)](8)[Dy(H2O)(4)](3)[Nb-24-O-69(H2O)(3)](2) . 36H(2)O (1) and H9K[Cu(en)(2)(H2O)](5)[Cu(en)(2)](4)-[Eu(H2O)(4)](3)[Nb24O69(H2O)(3)](2) . 2en . 45H(2)O (2) have been obtained under hydrothermal conditions. These extended materials are constructed from lanthanide-incorporated triangular-prism-like polyoxoniobate secondary building units (SBUs) {[Ln(H2O)(4)](3)[Nb24O69(H2O)(3)](2)} (Ln=Dy, Eu). 1 and 2 represent the first examples of high-dimensional polyoxometalate materials based on such lanthanide-incorporated triangular-prism-like polyoxoniobate SBUs. Furthermore, the proton conduction property and the luminescent emission of these materials were evaluated.
