文摘

•: Nature of M-PNR₂ bonds in the electrophilic phosphinidene complexes is investigated.
•: The M-PNR₂ bonds trans to PPh₃ ligand are shorter.
•: The electrostatic interactions ΔE_elstat are larger than the orbital interactions ΔE_orb.
•: The π-bonding contribution is much smaller than the σ-bonding.
•: ³¹P NMR chemical shifts of phosphinidene ligands are largest for rhodium complexes.
