Metathesis reactions of [PNP]Cl ([PNP] +  ≡ bis(triphenyl- λ  5 -phosphanylidene)ammonium) with Na 2 [SO 4 ] or K[HSO 4 ] in water yield [PNP] 2 [SO 4 ] and [PNP][HSO 4 ], respectively, as colorless solids. Reactions under basic conditions lead to a partial decomposition of the weakly coordinating [PNP] +  cation.  N -Diphenylphosphine-triphenylphosphazene, triphenylphosphinimine, and benzene were identified as decomposition products by NMR spectroscopy. The compounds [PNP] 2 [SO 4 ] and [PNP][HSO 4 ] were characterized by multinuclear NMR and vibrational spectroscopy. [PNP][HSO 4 ] could be crystallized from acetonitrile-diethyl ether giving single crystals with and without additional acetonitrile solvate molecules. The [HSO 4 ] −  anions form dimers in the solid state in both structures, which are held together by O–H⋯O hydrogen bonds. At  T  = 127 K the [HSO 4 ] −  anions in the crystal structure of solvate free [PNP][HSO 4 ] are ordered, while at  T  = 300 K and in the structure containing additional acetonitrile solvate molecules a disorder of the [HSO 4 ] −  anions over two positions is observed, for the latter even at 150 K.
