The authors report that Au(I) complexes containing dialkylbiphenylphosphane ligands show weak metal-arene interactions with the covering arene ring, and that these contacts are shorter than the limiting values found for isoleptic Ag(I) and Cu(I) complexes. Moreover, they describe dialkylbiphenylphosphane arene-Ag(I) complexes that have the strongest known Ag(I)-arene bonds.
