Two Novel Copper–Undecaniobates Decorated by Copper–Organic Cations [{Cu(H₂O)L}₂{CuNb₁₁O₃₅H₄}]⁵⁻ (L=1,10‐phenanthroline, 2,2′‐bipyridine) Consisting of Plenary and Monolacunary Lindqvist‐Type Isopolyniobate Fragments

Keep it in the family: Two novel copper–undecaniobates [{Cu(H2O)L}2{CuNb11O35H4}]5− (L=1,10-phenanthroline or 2,2′-bipyridine, an example is shown here) have been successfully synthesized by the diffusion strategy and, as far as we know, represent the first examples of copper–undecaniobates in the polyoxoniobate family.
