Twice the fun: Dimeric FeII diphosphonium bis(alkynyl) complexes are formed by oxidation of the corresponding FeII alkynyl phosphine complexes. The structure of these organometallic diphosphonium salts and their monomeric precursors were established by X-ray crystallography. The PP bond can be cleaved by two-electron reduction to regenerate the monomers.
