Abstract

We present a formally zero-valent compound, [Co(Mabiq)Na(OEt₂)]₂ (1). The complex was characterized by crystallographic, spectroscopic and DFT computational methods. The electronic structure is described as a Co^II-(ligand-biradical). Compound 1 is reactive toward proton sources; Co^I or Co^II products result, depending on the source of protons used. The redox non-innocence of the Mabiq ligand, which accepts both protons and electrons, has important ramifications for reactivity.
