Reactivity of a biomimetic W(iv) bis-dithiolene complex with CO2 leading to formate production and structural rearrangement

Abstract

A mononuclear W(IV) bis-dithiolene complex stabilized by an oxo ligand shows a reductive reactivity toward CO₂, from which formate and a dinuclear W(V) complex are generated. An unusual structural rearrangement was observed during the reaction. Structural and spectroscopic characterization for a novel triply bridged dinuclear W(V) complex is reported.
