The vapor phase formed by reaction of mixtures of aluminum, gold, and chlorine

A spectrophotometric study of mixed-metal dimers in vapors formed by reaction of Al, Au, and Cl₂ is presented. The absorbance of fully vaporized mixtures as well as the gas phase in equilibrium with Au(s) has been observed at various concentrations of Al₂Cl₆ and Cl₂. While AlAuCl₆(g) appears to be the dominant mixed-metal dimer, evidence is found suggesting the presence of molecules containing less chlorine, such as AlAuCl₅(g). Assuming both AlAuCl₆(g) and AlAuCl₅(g) are present, thermodynamic properties and UV-visible absorption spectra are derived.
