Tetramethylphosphonium Fluoride:  “Naked” Fluoride and Phosphorane

Inorganic Chemistry, 2003
Me(4)PF was investigated in the solid state, in the gas phase, and in solutions. Vibrational spectra of the solid and a single-crystal structure show an ionic tetramethylphosphonium fluoride. The compound crystallizes in the space group Pbca with a = 1016.0(1), b = 1018.0(1), c = 1205.8(4) pm, and Z = 8.

Absorption of Fluoride from Fluoride Dentifrices

Caries Research, 1980
The bioavailability of fluoride (F) from NaF and Na2PO3F dentifrices was studied in detail in young volunteers. The method used was based on a comparison of plasma and urinary data obtained following intravenous administration of a single 3-mg dose F and ingestion of 6 g (6 mg F) of two different F dentifrices on three separate occasions.

Bonding in Xenon Fluorides and Halogen Fluorides

Science, 1963
The bonding in rare gas fluorides is similar to that in halogen polyfluorides, and the stability of such compounds should depend primarily on the ionization potential of the central atom. This theory is consistent with findings for all known compounds of the system and yields predictions concerning other systems.

Fluoride and the fluoridation of water

1982
In the early years of this century a dentist in Colorado, Frederick McKay, observed that the permanent teeth of many of his patients showed either white chalky patches or lines which, in more severe cases, had a rough surface and, some years after eruption, became an unsightly yellow or brown. The condition was uncommon in the deciduous teeth.
