Abstract	A manganese containing polyoxometalate (POM) [Mn₃(H₂O)₃(SbW₉O₃₃)₂]¹²⁻(1) was synthesized and characterized in detail. The photocatalytic activity of 1 is definitely better than other manganese containing POM water oxidation catalysts reported so far according to oxygen yield, whereas the analogues [Mn₃(H₂O)₅(PW₉O₃₄)₂]^9- (2) and [Mn₃(H₂O)₃(SbW₉O₃₃)₂]¹²⁻(3) show no to slight photocatalytic O₂ evolution amount. Meanwhile, the electrocatalytic activities of 1-3 were investigated in 80 mM pH 9.0 borate buffer, which follows the catalytic activity order of 1 > 2 > 3. Multiple experiments including UV-vis absorption, catalysts aging experiments, tetra-n-heptylammonium nitrate (THpANO₃) toluene extraction, electrochemical experiments and capillary electrophoretic measurements results confirm that catalyst 1 is a homogeneous molecular catalyst. No Mn²⁺ (aq.) or manganese oxide under the reaction conditions of photocatalytic and electrochemical water oxidation was detected.
