Heating a metastable solution of GeIBr to room temperature led to the first structurally characterized metalloid subhalide cluster Ge14Br8(PEt3)4 (1). Furthermore 1 can be seen as the first isolated binary halide cluster on the way from GeIBr to elemental germanium, giving insight into the complex reaction mechanism of its disproportionation reaction. Quantum chemical calculations further indicate
将Ge I Br的亚稳态溶液加热至室温,导致产生第一个结构上表征的准
金属亚卤化物簇Ge 14 Br 8(PEt 3)4(1)。此外,从Ge I Br到元素
锗的过程中,1可以看作是第一个孤立的二元卤化物簇,从而深入了解了歧化反应的复杂反应机理。量子
化学计算进一步表明经典的键合情况是在1内实现的,形成1的最后一步可能包括捕获GeBr 2单元。
