The synthesis, metalation, and redox properties of an acyclic bis(iminothienyl)methene L⁻ are presented. This π‐conjugated anion displayed pronounced redox activity, undergoing facile one‐electron oxidation to the acyclic, metal‐free, neutral radical L^. on reaction with FeBr₂. In contrast, the reaction of L⁻ with CuI formed the unique, neutral Cu₂I₂(L^.) complex of a ligand‐centered radical, whereas reaction with the stronger oxidant AgBF₄ formed the metal‐free radical dication L^.2+.
