Resumen:
      Single crystals of Ag2PO3F were obtained from diluted aqueous solutions. The adopt a new structural type and crystallizes in the monoclinic C2/c space group with eight formula units in the unit cell. The compound was further characterized by vibrational (Raman and IR) and solid state (19)F, (31)P and (109)Ag MAS NMR spectroscopy. Thermal analysis (TG, DSC) revealed a reversible phase transition at 308 ºC, which is very close to the decomposition range of the compound. Under release of POF3, Ag4P2O7 and Ag3PO4 are the thermal decomposition products at temperature above 450 ºC.
