Phosphonium–betaine (ylide–carbene) complexes have been synthesised via nucleophilic attack by P(OR)3 on a σ-π-acetylide complex Fe2(CO)6(CCPh)(PPh2), and a single crystal X-ray study of the triethylphosphite derivative Fe2(CO)6{C[P(OEt)3]CPh}(PPh2) has con-firmed the presence of a new type of 2-carbon, 3-electron ligand.
