The impact of the strongly electron donating carbodiphosphorane moiety in the series of tri(phosphonio)methanide dications as triflate salts [(Ph₃P)₂CP(X)Ph₂][OTf]₂ (X = H, Me, CN, NCS, OH, Cl, OTf, F) deriving from [(Ph₃P)₂CPPh₂][OTf] (19[OTf]) is presented. The influence of the introduced substituents X on the electronic structures of these dications is investigated by means of detailed NBO analysis, NMR spectroscopy and X-ray analysis.
