摘要

A novel mixed-valence, ring-shaped multinuclear Mn-containing polyoxometalate, [H₂N(CH₃)₂]₁₅ NaH₈-[Mn^III₃Mn^IV(μ₃-O)₃(OAc)PO₄(B-α-PW₉O₃₄)]₄· 36H₂O (1) was made and systematically characterized using various spectroscopic and computational techniques. Its polyoxoanion can be described as a tetramer made of four [Mn^III₃Mn^IV(μ₃-O)₃(OAc) (B-α-PW₉O₃₄)]³⁻ ({Mn^III₃Mn^IV(PW₉)}) clusters and four PO₄ linkers. Significantly, this structurally new complex 1 can efficiently catalyze hydrogen evolution with 23 μmol H₂ gas after 12 h of visible-light irradiation using a three-component system. We propose a possible catalytic hydrogen-evolving mechanism based on both experimental results and density functional theory (DFT) calculations.
