ReO3-type structures can be described as ABX3 perovskites in which the A-cation site is unoccupied. They therefore have the general composition BX3, 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 WO3 and AlF3, 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 (ScF3), photocatalysis (CoSn(OH)6), thermoelectricity (CoAs3), and even superconductivity (SH3). We present a comprehensive account of this exciting family of materials and discuss current challenges and future opportunities in the area.
