ResumoAbstract The atomization energies, Δ H o,at 0 , of the molecules LuAu 2 , HoAu 2 and TbAu 2 were determined by means of high-temperature Kundsen-cell mass spectrometry as 143.9 ± 8, 131.1 ± 8 and 143.3 ± 8 kcal mole −1 , respectively. The measured atomization energies suggest the structure AuLnAu. They agree with the values calculated after the Pauling model by assuming two polar single bonds. The remaining rare-earth metals are also expected to form stable diaurides with atomization energies similar to those calculated after the Pauling model.
