| 摘要: 开发由金属In和Sn参与构筑的金属硫族非超四面体(non-Tn)团簇材料，对于实现该类材料的结构多样性及丰富其光电应用十分重要。利用溶剂热法合成了一系列新的non-Tn团簇化合物(C7H13N2)[InS2](1)、(C7H13N2)4[In2S11Sn3](2)和(C7H13N2)3[In3S12Sn3](3)，其中C7H13N2=质子化的1，5-二氮杂双环[4.3.0]壬-5-烯。3种化合物由{SnS4}、{InS4}或{InS5}三个配位单元之间以边共享或顶点共享的方式组合而成。电催化氧还原反应(ORR)研究表明，化合物1~3的还原峰电位分别为0.60、0.64和0.65 V，含有Sn（Ⅳ）的化合物2和3表现出更好的催化性能。不仅如此，Koutecky-Levich图分析表明，化合物中In和Sn的组成比例对其ORR催化路径有明显的调节作用。 |

| Abstract: The development of metal chalcogenide non-supertetrahedral (non-Tn) cluster materials composed of metal In and Sn is very important for realizing the structural diversity of the materials and enriching their photoelectric applications. Herein, a series of new non-Tn cluster-based compounds C7H13N2[InS2] (1), (C7H13N2)4[In2S11Sn3] (2), and (C7H13N2)3[In3S12Sn3] (3) were prepared by the solvothermal method, where C7H13N2=protonated 1,5-diazabicyclo [4.3.0]non-5-ene. The three compounds are formed by the combination of {SnS4}, {InS4}, or {InS5} coordination units in the way of edge-sharing or vertex-sharing. The electrocatalytic oxygen reduction reaction (ORR) study showed that the reduction peak potentials of compounds 1-3 were 0.6, 0.64, and 0.65 V, respectively, which indicates that compounds 2 and 3 containing Sn（Ⅳ） have better catalytic performance. More than that, the Koutecky-Levich plot analysis showed that the composition ratio of In and Sn in the compounds has a significant modulating effect on the ORR catalytic pathways. |
