[Ga@Bi10(NbMes)2]3−: a linear Nb–GaI–Nb filament coordinated by a bismuth cage†
Abstract
In this work, we report a low-valent Ga(I) complex, [Ga@Bi10(NbMes)2]3−, with a linear Nb–Ga–Nb fragment, representing the first compound with Nb–Ga and Nb–Bi bonds. Quantum-chemical calculations reveal that the complex is an electron-precise cluster. The possible fragmentation pathway of the title cluster was studied by using electrospray ionization mass spectrometry and theoretical calculations.
