Gas-phase generation of dinuclear Au(I)-Au(II) complexes by laser desorption ionization mass spectrometry. Issue 2 (August 2021) - Kasperkowiak, Małgorzata
Alkali metal chloroaurates(III) were analysed by laser desorption ionization mass spectrometry. Among a number of generated gas-phase ionic clusters, the unusual ions [MAu2 Cl5 ] - (were M stands for Na, K, Rb, Cs) were detected. The spectra of metastable ions and quantum mechanics calculations show the presence of unprecedented Au(I)-Au(II) interactions in the clusters.
