Aurophilicity
From Wikipedia, the free encyclopedia
Aurophilicity is a name given to the unusual ability of gold atoms to form weak gold-gold bonds, and is most commonly observed for Au(I) compounds. The aurophilic bond has a length of about 3.0 Å and a strength of about 7-12 kcal/mol, which is comparable to the strength of a hydrogen bond. The aurophilic interaction is considered to be largely based on electron correlation of the closed-shell components, somewhat similar to van der Waals interactions, but unusually strong due to relativistic effects.
