摘要
The dependence of the ''aurophilic'' attraction in the perpendicular model system (XAuPH(3))(2) on the substituent X is studied using 19-valence electron quasirelativistic pseudopotentials for Au. It increases along the series F<-CH3<H<Cl<-CN<Br<I<-SCH3, reaching 25 kJ/mol for the softest ligand, X. The calculated range, R(e), depth, V(R(e)), and Au...Au force constant are comparable with available experimental values.
