The heteronuclear Au^I/Hg^II complexes [Hg{AuR(渭-2-C₆H₄PPh₂)}₂] [R = C₆F₅ (1), C₆Cl₂F₃ (2)] were prepared by reacting [Hg(2-C₆H₄PPh₂)₂] with [AuR(tht)] (1:2) and further transformed into the Au^III/Hg^II species [Hg{Au(C₆F₅)Cl₂(渭-2-C₆H₄PPh₂)}₂] [R = C₆F₅ (3), C₆Cl₂F₃ (4)] by the addition of 2 equiv of PhI路Cl₂. The crystal structures of 1鈥?b>3 display Au路路路Hg^II interactions, which in the case of 3 is the first Au^III路路路Hg contact described to date. Theoretical calculations on model systems of the C₆F₅ derivatives evidence that the attraction between Au^I or Au^III and Hg^II arise from dispersion-type interactions and that both contacts are of the same strength.
