    Abstract: A method for purifying a crude PNPNH compound of the general structure R1R2P—N(R3)—P(R4)—N(R5)—H wherein R1, R2, R3, R4 and R5 are independently halogen, amino, trimethylsilyl, C1-C10-alkyl, substituted C1-C10-alkyl, C6-C20-aryl and substituted C6-C20-aryl, or any cyclic derivative wherein at least one of the P or N atoms of the PNPN—H structure is a member of a ring system, the ring system being formed from one or more constituent compounds of the PNPNH-structure by substitution, the method comprising the steps: A. a) dissolving the crude PNPNH-compound in a C1-C10 alcohol or mixture thereof under heating; b) cooling the solution obtained in step a), c) precipitating the PNPNH compound, separating and optionally drying, or B. (i) washing the crude PNPNH compound with C1-C10 alcohol or a mixture thereof, (ii) separating the PNPNH compound and optionally drying thereof.
