Abstract = {{Recent theoretical predictions of ``unprecedented proximity{''} of the
   electronic ground state of iridium fluorides to the SU(2) symmetric
   j(eff) = 1/2 limit, relevant for superconductivity in iridates,
   motivated us to investigate their crystal and electronic structure. To
   this aim, we performed high-resolution x-ray powder diffraction, Ir
   L-3-edge resonant inelastic x-ray scattering, and quantum chemical
   calculations on Rb-2{[}IrF6] and other iridium fluorides. Our results
   are consistent with the Mott insulating scenario predicted by Birol and
   Haule {[}Phys. Rev. Lett. 114, 096403 (2015)], but we observe a sizable
   deviation of the j(eff) = 1/2 state from the SU(2) symmetric limit.
   Interactions beyond the first coordination shell of iridium are
   negligible, hence the iridium fluorides do not show any magnetic
   ordering down to at least 20 K. A larger spin-orbit coupling in iridium
   fluorides compared to oxides is ascribed to a reduction of the degree of
   covalency, with consequences on the possibility to realize
   spin-orbit-induced strongly correlated physics in iridium fluorides.}},
