“…Inorganic monofluorophosphates(V), M I 2 PO 3 F· x H 2 O and M II PO 3 F· x H 2 O, are important materials used as toothpaste additives, wood preservatives, corrosion inhibitors, solubility inhibitors for lead in potable water sources, and as active agents against osteoporosis or caries during biomineralization of fluoroapatite . Therefore, much effort has been paid in the past to the preparation and structural characterization of these compounds.…”

Single crystals of disilver(I) monofluorophosphate(V), Ag2PO3F (1), were obtained by slow evaporation of a diluted aqueous Ag2PO3F solution. Compound 1 adopts a new structure type and crystallizes in the monoclinic space group C2/c with eight formula units and lattice parameters of a = 9.2456(8) A, b = 5.5854(5) A, c = 14.7840(13) A, and beta = 90.178(2) degrees. The crystal structure of 1 [R(F2 > 2sigma(F2) = 0.0268, wR(F2 all) = 0.0665] is composed of three crystallographically independent Ag+ cations and PO3F2- anions as single building units. The oxygen environment around each of the Ag+ cations is different, with one Ag+ in distorted octahedral (d(Ag-O) = 2.553 A), one in nearly rectangular (d(Ag-O) = 2.445 A), and one in distorted tetrahedral (d(Ag-O) = 2.399 A) coordination. Additional Ag-F contacts to more remote F atoms located at distances >2.80 A augment the coordination polyhedra for the two latter Ag+ cations. The monofluorophosphate anion deviates slightly from C3v symmetry and exhibits the characteristic differences in bond lengths, with a mean of 1.510 A for the P-O bonds and one considerably longer P-F bond of 1.575(2) A. Compound 1 was further characterized by vibrational spectroscopy (Raman and IR) and solid-state 19F, 31P, and 109Ag MAS NMR spectroscopy. The value for the isotropic one-bond P-F coupling constant in 1 is 1JPF = -1045 Hz. Thermal analysis (TG, DSC) revealed a reversible phase transition at 308 degrees C, which is very close to the decomposition range of 1. Under release of POF3, Ag4P2O7 and Ag3PO4 are the thermal decomposition products at temperatures above 450 degrees C.

“…14,17,18 It is believed that enamel biopsy provides a direct measurement as one of the most reliable techniques for measuring F + level of enamel. 19,20 Root and Schreiber 20 reported that long-term use of fluoride rinse has a greater chance of F + uptake by enamel than short periods, indicating a more reliable preventive role when fluoride rinse is used regularly. It is worth pointing out that the use of enamel biopsy, which was first introduced by McCann, 12 has frequently been reported to be used by many researchers who have employed 0.5 mol perchloric acid for 30 seconds.…”
