Abstract

Abstract: Treatment of two equivalents of the triphosphenium zwitterionL with sources of Ni 0 and Pd 0 form the mononuclear η 2 ‐diphosphoniodiphosphene complexes1 and2 . The reaction betweenL and [FeCp(CO)2 ]2 results in the binuclear μ‐η 1 :η 1 ‐diphosphoniodiphosphene iron complex3, 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. Abstract : A diphosphoniodiphosphene is unexpectedly formed by insertion of Ni 0, Pd 0, and Fe I into the P−P bonds of a triphosphenium zwitterion, giving rise to structurally confirmed μ 2 ‐bound monometallic or μ‐η 1 :η 1 ‐bimetallic species.
