  Synthesis and characterization by Raman spectroscopy of AsBr₄AsF₆; its thermodynamic and kinetic stability and that of related salts

  摘要：

  The thermodynamically and kinetically unstable salt AsBr4AsF6 was prepared by the reaction of stoicheiometric quantities of AsBr3, Br2, and AsF5, and characterized by Raman spectroscopy at -196-degrees-C. It was shown by Raman spectroscopy that AsBr4AsF6 decomposes to AsF3 and Br2 via AsBr3. The energetics of the formation and decomposition have been estimated, and reaction pathways suggested. Simple estimates of the energetics of the formation of AsBr4AlBr4 showed it should have greater stability than that of AsBr4AsF6; it was subsequently prepared but shown to be in equilibrium at room temperature with AsBr3, Br2, and AsBr4Al2Br7. The differences in thermodynamic stability of AsCl4AsF6 and AsBr4AsF6 have been accounted for, and reasons for the kinetic instability of AsBr4AsF6 proposed.
