Aurophilicity: the effect of the neutral ligand L on [{ClAuL}(2) ] systems.
摘要：
The effect of the ligand L on the aurophilic AuIAuI closed-shell interaction in perpendicular [{ClAuL}2] model systems is investigated. An analogous study of the effect of the halide X (here Cl) exists, and showed a correlation with the softness of the ligand X. In this work, we study the correlation with L=N-heterocyclic carbenes (NHC), cyclic diphosphinocarbenes (PHC), NF3, CO, methyl isocyanide CNMe, PF3, SH2, NH3, H2O, pyridine, triazene, the carbodiphosphorene model C(PH3)2, C3H2, and the related model systems CN2 or CP2. The NHCs yield stronger interactions than PH3. The spatial orientation of certain ligands in a paddle configuration plays an important role on the strength of the interaction. All are examples on aurophilicity.
