摘要

A polyanion cluster H₆Na₈Cs₃[Co₉(μ₃-OH)₃(H₂O)₆(HPO₄)₂(B-α-PW₉O₃₄)₃]Cl·40H₂O (1) was made with the guidance of the lacunary directing strategy under hydrothermal conditions. Compound 1 was characterized by single-crystal X-ray diffraction, powder X-ray diffraction, and thermogravimetric analysis, respectively. Single-crystal X-ray diffraction analyses showed that 1 consists of three anions [B-α-PW₉O₃₄]⁹⁻ and a cyclic cationic [Co₉(μ₃-OH)₃(H₂O)₆]¹⁵⁺ and two anions HPO₄²⁻. Variable-magnetic properties indicate antiferromagnetic interactions in 1. Visible-light-driven hydrogen evolution tests demonstrated that 1 was an efficient water reduction catalyst with an H₂ evolution rate of 1217.6 μmol h⁻¹ g⁻¹.
