A new form of FeF3 with the pyrochlore structure : Soft chemistry synthesis, crystal structure, thermal transitions and structural correlations with the other forms of FeF3

The very strong solid Lewis acids aluminium chlorofluoride (ACF) and bromofluoride (ABF)—Synthesis, structure, and Lewis acidity

“…Postfluorination of the ''gallium chlorofluoride'' with gaseous HF or CHClF 2 at elevated temperatures leads to crystalline a-GaF 3 and h-GaF 3 , respectively. The latter phase is isotypic to h-AlF 3 [34] and h-FeF 3 [48] with pyrochlore structure. It has never been observed before and was synthesised for the first time.…”

A Hybrid Solid with Giant Pores Prepared by a Combination of Targeted Chemistry, Simulation, and Powder Diffraction

“…The subnetwork that joins these centers forms corner-linked tetrahedra as in the pyrochlore structure. [17] The dodecahedra share faces and form (see the Supporting Information) infinite linear rodlike chains, [18] which cross orthogonally to each other through common faces to ensure the 3D network. This connection creates larger cavities, which have 28 ST.…”

NaCaNi2F7: A frustrated high-temperature pyrochlore antiferromagnet withS=1NKrizan1, Cava2 2015Phys. Rev. B484550View full textAdd to dashboardCite

“…[13][14][15][16] There is theoretical interest in the FeF 3 pyrochlore, but unfortunately, the methods employed for its synthesis likely preclude the growth of this material as large single crystals. 15,17,18 In contrast, the S = 1 NaCaNi 2 F 7 and S = 3/2 NaCaCo 2 F 7 and NaSrCo 2 F 7 fluoride pyrochlores have now been grown as cm-scale single crystals, suggesting that transition metal fluorides have the potential to develop into a significant and readily accessible new family of geometrically frustrated magnets. 4,5 …”
