NH 4 [PO 2 F(NH 2 )] has been prepared by the reaction of a betaine py·PO 2 F with excess ammonia in acetonitrile solution, while the ammonolysis of DMAP·PO 2 F with a stoichiometric amount of NH 3 yields [DMAPH][PO 2 F(NH 2 )]. The crystal structure of the latter was determined by single-crystal X-ray diffraction, which revealed that the anions [PO 2 F(NH 2 )] Ϫ are linked to infinite chains by double NϪH···O bridges. Additional strong NϪH···O
Synthese von Ammonium-und 4-Dimethylaminopyridinium-Amidofluorophosphaten und die Kristallstruktur von [DMAPH][PO 2 F(NH 2 )]Inhaltsübersicht. NH 4 [PO 2 F(NH 2 )] wurde durch Umsetzung des Betains py·PO 2 F in acetonitrilischer Lösung mit überschüssigem NH 3 dargestellt, während bei der Ammonolyse von DMAP·PO 2 F mit einer stöchiometrischen Menge von Ammoniak [DMAPH]-[PO 2 F(NH 2 )] entsteht. In der Kristallstruktur von [DMAPH]-[PO 2 F(NH 2 )] sind die Anionen durch doppelte Wasserstoff-Brü-* Dr. Miloš Č erník
