Treatment of two equivalents of the triphosphenium zwitterion L with sources of Ni 0 and Pd 0 form the mononuclear η 2 ‐diphosphoniodiphosphene complexes 1 and 2 . The reaction between L and [FeCp(CO) 2 ] 2 results in the binuclear μ‐η 1 :η 1 ‐diphosphoniodiphosphene iron complex 3 , which features an alternative bonding motif of the diphosphoniodiphosphene unit. The formation of these species has been confirmed by spectroscopic methods and single‐crystal X‐ray diffraction analysis, and their electronic structures have been elucidated using computational methods.
