Abstract

Abstract : The reaction of a non‐symmetrical pyridine‐NHC‐phosphane (NĈP) ligand – generated in situ upon the deprotonation of the corresponding imidazolium salt – with equimolar amount of [Cu(NCMe)4 ](BF4 ) or Mn2 (CO)10 leads to the formation of bimetallic complexes [Cu2 (NĈP)2 (NCMe)](BF4 )2 and [Mn2 (CO)7 (NĈP)], respectively, in which the tridentate ligand exhibits an unusual µ‐κ 2 Ĉ, N ‐M;κ 1 P ‐M coordination mode. According to NMR spectroscopy and mass spectrometry, the binuclear copper complex is in equilibrium in MeCN solution with two mononuclear species, namely [Cu(κ 2 Ĉ, P ‐NĈP)2 ](BF4 ) and [Cu(κ 3 ‐ N, Ĉ, P ‐NĈP)(NCMe)](BF4 ). Abstract : Binuclear transition metal complexes bearing pyridine‐NHC‐phosphane ligand in bridging µ‐κ 2 Ĉ, N ‐M;κ 1 P ‐M coordination mode were prepared in good yields. The complexes were fully characterized by spectroscopic and X‐ray diffraction techniques.
