Bis(triphenylphosphine)iminium chloride is the chemical compound with the formula [((C₆H₅)₃P)₂N]Cl, often abbreviated [(Ph₃P)₂N]Cl, where Ph is phenyl C₆H₅, or even abbreviated [PPN]Cl or [PNP]Cl or PPNCl or PNPCl, where PPN or PNP stands for (Ph₃P)₂N. This colorless salt is a source of the [(Ph₃P)₂N]⁺ cation (abbreviated PPN⁺ or PNP⁺), which is used as an unreactive and weakly coordinating cation to isolate reactive anions. [(Ph₃P)₂N]⁺ is a phosphazene.
