Abstract
A novel mixed-valence, ring-shaped multinuclear Mn-containing polyoxometalate, [H2N(CH3)2]15 NaH8-[MnIII3MnIV(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 [MnIII3MnIV(μ3-O)3(OAc) (B-α-PW9O34)]3− ({MnIII3MnIV(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.
