Abstract

The dominant gaseous complexes YAl₃Br₁₂ and YAl₃I₁₂ were generated in the chemical transport reactions of YBr₃ with AlBr₃ and YI₃ with AlI₃. The enthalpy of formation

ΔH⁰_B(YAl₃Br_12,g,298) = -484,5 ± 6 kcal/mol

and the standard entropy

S°(YA₁₃B_12,g,298) = 290,0 ± 7,5 cal/K·mol

have been calculated. It follows from total pressure measurements of mixtures of YBr_3,s with AlBr_3,1 and YI_3,s with AlI_3,1 respectively, that complexes YAl₃Br_12,s and YAl₃I_12,s do not exist up to the boiling points of the aluminium trihalides.

Keywords: Chemical Transport Reaction; Yttrium Aluminium Halides; Enthalpy of Formation; Standard Entropy; Total Pressure Measurements
