Description
Abstract
The first dinuclear Au(I) compounds containing bridging (CF2)n chains (n = 4, 6, 8) and Au(III) metallaperfluorocyclopentanes have been obtained by photoinitiated reactions of LAuMe (L = PPh3, PMe3, PCy3 or IPr) with alpha,omega-diiodoperfluorocarbons. Complexes LAu(CF2)4AuL present an unusual looped structure stabilized by an aurophilic interaction for L = PMe3, PPh3 and PCy3. The study of their dynamic behaviour has provided new insights about the strength of aurophilic interactions in solution, allowing quantification of the energy of a single Au···Au interaction
