Resumen
Complex {[Hg(C6F5)2][Au(C 6F5)(PMe3)]2}n2 displays unsupported Au(i)⋯Hg(ii) and Au(i)⋯Au(i) interactions. Its crystal structure displays a polymeric -(Au-Hg-Au-Au-Hg-Au)n- disposition. Ab initio calculations show very strong Au(i)⋯Hg(ii) and Au(i)⋯Au(i) closed-shell interactions of -73.3 kJ mol-1 and -57.0 kJ mol-1, respectively, which have a dispersive (van der Waals) nature and are strengthened by large relativistic effects (>20%). © 2011 The Royal Society of Chemistry.
