通过[Re 6S 8（HCOO）（6）]（4-）与甲酸在水溶液中的室温反应，合成了末端为甲酸根配体的六铼阴离子簇合物[Re 6S 8（HCOO）（6）]（4-）。该簇以钾或铯盐的形式结晶，并通过X射线单晶衍射和元素分析、IR、H-1 NMR、UV/维斯和发光光谱对其进行了表征。特别地，首次测定了Re-6簇阴离子钾盐在固相中的发射量子产率。通过密度泛函理论计算，确定了[Re 6S 8（HCOO）（6）]（4-）和[Re 6S 8（HCOO）（6）]（4-）的电子结构.
The hexarhenium anionic cluster complex with terminal formate ligands [Re6S8(HCOO)(6)](4-) was obtained by the room-temperature reaction between [Re6S8(HCOO)(6)](4-) and formic acid in an aqueous solution. The cluster was crystallized as a potassium or cesium salt and characterized by X-ray single-crystal diffraction and elemental analyses, IR, H-1 NMR, UV/vis, and luminescence spectroscopies. In particular, the emission quantum yield of the potassium salt of the Re-6 cluster anion in the solid phase was determined for the first time. The electronic structures of [Re6S8(HCOO)(6)](4-) and [Re6S8(HCOO)(6)](4-) were also elucidated by DFT calculations.
