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°(ReF7(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°(IF7(g) → IF6+(g) + F-(g))= 870 ± 24 kj mole-1(208 ± 6 kcal mole-1).
