We present here a relativistic density functional theory investigation of the penta- and heptavalent states of gold and roentgenium, employing the ZORA (zeroth order regular approximation to the Dirac equation) Hamiltonian, including spin-orbit coupling at the two-component level, and large all-electron relativistic Slater-type quadruple-zeta quadruple polarization (ZORA-STO-QZ4P) basis sets. Unsurprisingly, our calculations confirm the stability of the experimentally known complexes AuF6- and Au2F10 with respect to decomposition to trivalent Au products and F-2. The calculations also predict that RgF(6)(-) and Rg(2)F(10) should be even more stable with respect to an analogous decomposition pathway. Like an earlier DFT study (Inorg. Chem.2007, 46 (13), 5338-5342), our calculations rule out the true heptavalent Au complex AuF7 as a stable species, preferring instead a C-s AuF5 center dot center dot center dot F-2 formulation. Remarkably, our calculations confirm a D-5h pentagonal-bipyramidal structure of RgF(7) as the global minimum, at an energy of approximately half an electron volt below the RgF(5)center dot center dot center dot F-2 form.
