More than 50 years after the proposal of the Dewar–Chatt–Duncanson model for the binding of olefins to transition-metal atoms, the first structurally characterized example of a silver–C2H4 complex ([Ag(η2-C2H4)3]+, see picture) was obtained with the help of the very weakly coordinating [Al{OC(CF3)3}4]− ion. By contrast, earlier gas-phase investigations only suggested the existence of [Ag(η2-C2H4)x]+ ions (x=1 and 2).
