Abstract

Complex {[Hg(C6F5)2][Au(C6F5)(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%).
