A facile route to ‘naked’ Ag <sup>+</sup> ions enabling the coordination of the weak Lewis base Ni(CO) <sub>4</sub>
The reaction of AgCN with two equivalents of tris(pentafluorophenyl)borane (BCF) in CH<sub>2</sub>Cl<sub>2</sub> or <i>ortho</i>-difluorobenzene (<i>o</i>DFB) provides a straightforward access to (solvated) Ag<sup>+</sup> salts of the weakly coordinating cyanide-bridged anion [µ-(CN)(BCF)<sub>2</sub>]<sup>-</sup> (suggested abbreviation [BCNB]). Reacting Ag[BCNB] with Ni(CO)<sub>4</sub> yields the first structurally characterized complex in which Ni(CO)<sub>4</sub> acts as a ligand towards a transition metal ion proving the extremely low basicity of the anion.
