“…137 and MgTi 2 OF 8 . 141 The ReO 3 -type oxyfluorides have been primarily studied as intercalation materials for use in batteries, 135,136 with the greater class of oxyfluorides viewed as a favorable middle ground between oxides and fluorides, leveraging the high voltage levels of the fluorides and increased stability of the oxides (due to the more covalent M-O bonds).…”

ReO 3-type structures can be described as ABX 3 perovskites in which the A-cation site is unoccupied. They therefore have the general composition BX 3 , where B is normally a cation and X is a bridging anion. The chemical diversity of such structures is very broad, ranging from simple oxides and fluorides, such as WO 3 and AlF 3 , to more complex systems in which the bridging anion is polyatomic, as in the Prussian blue-related cyanides such as Fe(CN) 3 and CoPt(CN) 6. The same topology is also found in metal-organic frameworks, for example In(Im) 3 (Im = imidazolate), and even the well-known MOF-5 structure, where the B-site cation is itself polyatomic. This remarkable chemical diversity gives rise to a wide range of interesting and often unusual properties, including negative thermal expansion (ScF 3), photocatalysis (CoSn(OH) 6), thermoelectricity (CoAs 3), and even a report of superconductivity in a phase that is controversially described as SH 3 with a doubly interpenetrating ReO 3 structure. We present a comprehensive account of this exciting family of materials and discuss current challenges and future opportunities in the area.

Syntheses and Crystal Structures of New ReO 3-Type-Derived Transition Metal Oxide Fluorides. -MNb 2O3F6 (M: Mg, Zn), MgM2OF8 (M: Ti, Zr), Fe2TiO8F, and TiNb 2O5F4 are prepared by stirring the corresponding phase pure mixed-metal oxides in a 1:1 mixture of 48% aq. HF and 48% aq. HNO3 (Teflon beaker, 25 C, 1 d). MNb 2O3F6-type compounds crystallize in the cubic ReO3 type (space group Pm3m, Z = 1, powder XRD), MgTi 2OF8 and MgZr2OF8 in the cubic NaSbF6 type (space group Fm3m, Z = 8), and Fe2TiOF8 in the rhombohedral VF3 type (space group R3c, Z = 3). Structures of all compounds are explained and their refined structural parameters are given. -(NAKHAL*, S.; BREDOW, T.; LERCH, M.; Z. Anorg. Allg. Chem. 641 (2015) 6, 1036-1042, http://dx.
