Resumen

The heteronuclear AuI/HgII complexes [Hg{AuR(μ-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/HgII species [Hg{Au(C6F5)Cl 2(μ-2-C6H4PPh2)}2] [R = C6F5 (3), C6Cl2F3 (4)] by the addition of 2 equiv of PhI·Cl2. The crystal structures of 1-3 display Au···HgII interactions, which in the case of 3 is the first AuIII···Hg contact described to date. Theoretical calculations on model systems of the C 6F5 derivatives evidence that the attraction between AuI or AuIII and HgII arise from dispersion-type interactions and that both contacts are of the same strength. © 2014 American Chemical Society.
