Abstract

Alkali metal chloroaurates(III) were analysed by laser desorption ionization mass spectrometry. Among a number of generated gas-phase ionic clusters, the unusual ions [MAu₂Cl₅]^- (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.

激光解吸电离质谱法气相生成双核Au(I)-Au(II)配合物。

采用激光解吸电离质谱法对碱金属氯金酸酯(III)进行了分析。在生成的许多气相离子簇中，检测到异常离子[MAu2Cl5]-(其中M代表Na, K, Rb, Cs)。亚稳离子光谱和量子力学计算表明，在团簇中存在前所未有的Au(I)-Au(II)相互作用。
