The gold(i)···lead(ii) interaction: a relativistic connection

The crystal structure of complex [Pb{HB(pz)(3)}Au(C(6)Cl(5))(2)] 1 displays an unsupported Au(i)···Pb(ii) interaction. This complex emits at 480 nm in the solid state due to an aurate(i) to lead(ii) charge transfer, in which the existence of a metallophilic interaction is a pre-requisite. Ab initio...

Descripción
Sumario:The crystal structure of complex [Pb{HB(pz)(3)}Au(C(6)Cl(5))(2)] 1 displays an unsupported Au(i)···Pb(ii) interaction. This complex emits at 480 nm in the solid state due to an aurate(i) to lead(ii) charge transfer, in which the existence of a metallophilic interaction is a pre-requisite. Ab initio calculations show a very strong Au(i)···Pb(ii) closed-shell interaction of –390 kJ mol(–1), which has an ionic plus a dispersive (van der Waals) nature strengthened by large relativistic effects (>17%).
