Abstract

Detection of cesium auride (CsAu) by mass spectrometry represents the first success in the study of systems of two metals with a large difference in electronegativity. The fragmentation energy yields a value of D (CsAu) ≈ 460 ± 30 kJ/mol for the bond energy. The stability of CsAu is determined mainly by an ionic bonding component.
