In this work, two rare high‐dimensional polyoxoniobates with formulas of H 9 [Cu(en)(H 2 O) 2 ][Cu(en) 2 ] 8 [Dy(H 2 O) 4 ] 3 [Nb 24 ‐O 69 (H 2 O) 3 ] 2 ⋅ 36H 2 O ( 1 ) and H 9 K[Cu(en) 2 (H 2 O)] 5 [Cu(en) 2 ] 4 ‐[Eu(H 2 O) 4 ] 3 [Nb 24 O 69 (H 2 O) 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(H 2 O) 4 ] 3 [Nb 24 O 69 (H 2 O) 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.
