Synthesis and structure of the new oxide fluoride Sr2TiO3F2 from the low temperature fluorination of Sr2TiO4: an example of a staged fluorine substitution/insertion reaction

Fluorine insertion reactions into pre-formed metal oxides

“…A similar structure was soon observed for Sr 2 TiO 3 F 2 [22]. This was first observed in the n = 1 material LaSrMnO 4 F [30].…”

“…Again, additional anions occupied interstitial sites in the rocksalt layers. However, an unusual staged arrangement of anions in the interstitial sites was observed, in which alternate layers of interstitial sites within the rocksalt blocks were completely filled, with layers in between being unoccupied [22]. Work on this titanium oxide led to the use of poly(vinylidene fluoride) (PVDF) as a new low temperature fluorinating agent.…”

Fluorination of La2−xSrxCuO4 (x=0, 0.15, 0.3) and study on the crystal structures, magnetic properties of their fluorinated products

“…Recently, organic polyvinylidene fluoride (PVDF) [16][17][18][19][20][21][22][23] and polytetrafluoroethylene (PTFE) [24,25] were widely used as fluorinating agents and usually reacted at a temperature higher than 350°C, and limits their applications, because many oxyfluoride materials are instable at high temperature. Compared with above described fluorination techniques, transition metal di-fluorides as efficient and versatile fluorinating agent were also used widely [26][27][28][29][30][31]. This route is quite powerful and hardly http://dx.doi.org/10.1016/j.jallcom.2014.12.027 0925-8388/Ó 2014 Elsevier B.V. All rights reserved.…”

Oxyfluoride Chemistry of Layered Perovskite Compounds

“…This type of fluorination, especially in Cu oxides, has already been reviewed in detail by Greaves et [38], and nitride-fluoride Ce 2 MnN 3 F 2−δ [39].…”
