Abstract

Iridium hexafluoride oxidizes ReF₆ (via an ReF₆⁺ salt) and at room temperatures IrF₆, ReF₆, ReF₇ and (IrF₅)₄ are each present in the equilibrium mixture. From these and related findings: ΔH°(ReF₆ → ReF₆⁺ + e^-) 1092 ± 27 kj mole^-1(261 ± 6 kcal mole^-1), and thermodynamic data are selected to yield ΔH°(ReF_7(g) → ReF₆⁺_(g) + F^-_(g))=893 ± 33 kj mole^-1(213 ± 8 kcal mole^-1). From observations on the stability of IF₆⁺BF₄^- and the lattice enthalpy evaluation for the salt, ΔH°(IF_7(g) → IF₆⁺_(g) + F^-_(g))= 870 ± 24 kj mole^-1(208 ± 6 kcal mole^-1).
