Abstract

A CSD analysis and DFT study reveal that the nitrogen lone-pair in [N(PPh₃)₂]⁺ is partially intact and involved in intramolecular hydrogen bonding. Computations with the model cation [N(PMe₃)₂]⁺ indicate that intermolecular hydrogen bonding with this ion's N-atom is possible (−8.3 kcal mol⁻¹ for H₂O as hydrogen bond donor), presenting a rare example of pseudo anti electrostatic hydrogen bonding.
