Iron pentacarbonyl ligands on silver scorpionates

Chem Commun (Camb). 2022 Mar 3;58(19):3222-3225. doi: 10.1039/d1cc06859h.

Abstract

Fluorinated tris(pyrazolyl)borate supporting ligands enable the stabilization of silver(I) bonded to a neutral, organometallic Fe(CO)5 ligand. The Ag-Fe interaction in these molecules is mainly electrostatic in nature, but σ-donor and backbonding contributions between the two metal fragments also play notable roles, which can be modulated by the scorpionate substituents.
