using Au(I) precursors and AlCp*. The cluster [Au2(AlCp*)5] = [Au2Al5](Cp*)5 (3) was isolated and identified as an intermediate species in the reactions to 1 and 2. The processes of cluster growth and degradation were investigated by in situ 1H NMR and LIFDI-MS techniques. The structures of 1 and 2 were established by DFT geometry optimization. These octahedral clusters can both be described as closed-shell
簇合成的关键策略包括使用调节剂(例如配位添加剂)。我们研究了具有不同空间和电子特性的各种膦对 Au(I) 前体还原为 Au(0) 簇的影响。我们报道了双
金属簇 [Au 6 (AlCp*) 6 ] = [Au 6 Al 6 ](Cp*) 6 ( 1 ) 和 [HAu 7 (AlCp*) 6 ] = [HAu 7 Al 6 ](使用 Au(I) 前体和 AlCp* 得到 Cp*) 6 ( 2 ) (Cp* = 五
甲基环戊二烯)。簇[Au 2 (AlCp*) 5 ] = [Au 2 Al 5 ](Cp*) 5 ( 3 )被分离并鉴定为1和2反应中的中间物质。通过原位1 H NMR 和 LIFDI-MS 技术研究了簇的生长和降解过程。 1和2的结构是通过DFT几何优化建立的。这些八面体簇都可以描述为闭壳 18 电子超原子。
