将 GeI Br 的亚稳态溶液加热至室温，得到第一个具有结构特征的准金属低卤化物簇 Ge14 Br8 (PEt3 )4 (1)。此外，1可以被视为从GeI Br到单质锗的过程中第一个孤立的二元卤化物团簇，使人们能够深入了解其歧化反应的复杂反应机制。量子化学计算进一步表明，经典的键合情况在1内实现，并且1形成的最后一步可能包括捕获GeBr2单元。
Heating a metastable solution of GeI Br to room temperature led to the first structurally characterized metalloid subhalide cluster Ge14 Br8 (PEt3 )4 (1). Furthermore 1 can be seen as the first isolated binary halide cluster on the way from GeI Br to elemental germanium, giving insight into the complex reaction mechanism of its disproportionation reaction. Quantum chemical calculations further indicate that a classical bonding situation is realized within 1 and that the last step of the formation of 1 might include the trapping of GeBr2 units.
