Similar schematic figures have been previously reported for group 10 hexafluorides and group 9 monoanionic hexafluorides namely that d 4 -type configurations predict octahedral symmetries, but they did not explicitly mention the triplet spin-state at the SF level. Furthermore, the influence of the SOC on the electron affinity (EA) discussed in ref 33 can also be rationalized with reference to Figure . By adding the SO correction, these authors demonstrated that the EA of OsF 6 becomes smaller than that of IrF 6 . From Figure , the added electron predominantly occupies the e 5/2,g spinor of IrF 6 in the SO level, which is energetically higher compared to the one at the SF level, where it occupies the triply degenerate t 2g orbitals.
