摘要
The polynuclear manganese complexes play an important role in the oxygen evolution process of green plant photosynthesis. Among the trinuclear manganese complexes, [Mn<sub>3</sub>O（C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>）<sub>6</sub>L<sub>3</sub>]<sup>0,+</sup> type（L=Py, H<sub>2</sub>O）is reported more frequently in modern literature. Here, we report the synthesis and the characterization of three new types of oxo-
