摘 要：A gigantic Co₁₄-containing 36-niobate, Na₁₂K₈[Co₁₄(OH)₁₆(H₂O)₈Nb₃₆O₁₀₆]·71H₂O (1), has been prepared by the hydrothermal method and structurally characterized. Polyanion [Co₁₄(OH)₁₆(H₂O)₈Nb₃₆O₁₀₆]^20- (1a) comprises a central Co₇ core, surrounded by another seven isolated Co²⁺ ions and six Lindqvist-type (Nb₆O₁₉) hexaniobate fragments. This is the first example of a high-nuclear cobalt-cluster-containing polyoxoniobate. The photocatalytic H₂ evolution activity of Pt-loaded 1 was observed in methanol solution under irradiation using a 300 W Xe lamp.
