“…This contrasts with the bonding seen for formate perovskites, or the analogous hypophosphite perovskites and ReO3-type structures. (219,220,221) Understandably, the possibility of several bonding modes makes designing a layered structure difficult, as the formation of a more extended and complex structure may result depending on the metal and A-site cation of choice. However, multiple X -site anions can be included to diminish this effect.…”

Successful strategies for the design of crystalline materials with useful function are frequently based on the systematic tuning of chemical composition within a given structural family. Perovskites with the formula ABX3, perhaps the best-known example of such a family, have a vast range of elements on A, B, and X sites, which are associated with a similarly vast range of functionality. Layered double perovskites (LDPs), a subset of this family, are obtained by suitable slicing and restacking of the perovskite structure, with the additional design feature of ordered cations and/or anions. In addition to inorganic LDPs, we also discuss hybrid (organic-inorganic) LDPs here, where the A-site cation is a protonated organic amine. Several examples of inorganic LDPs are presented with a discussion of their ferroic, magnetic, and optical properties. The emerging area of hybrid LDPs is particularly rich and is leading to exciting discoveries of new compounds with unique structures and fascinating optoelectronic properties. We provide context for what is important to consider when designing new materials and conclude with a discussion of future opportunities in the broad LDP area. Expected final online publication date for the Annual Review of Materials Science, Volume 51 is August 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…This is seen in the cyanides and the thiocyanates, though the cavity in the hypophosphites appears to be too small for even monatomic neon. 196 Since the cavities defined by the larger molecular X sites may even be large enough to deliver permanent porosity, there is a significant similarity between such systems and metal-organic frameworks (MOFs). It is not surprising, therefore, to find that there are several examples of ReO 3 -type materials in which the linker is an organic anion, and such materials can be properly regarded as MOFs.…”

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.

Hybrid organic-inorganic perovskites: a spin-off of oxidic perovskites

ABX3 compounds with perovskite structure have been intensively and extensively studied in the last decades in view of their structural richness and amazing variety of interesting properties, such as piezoelectricity, ferroelectricity, ferromagnetism, superconductivity, magnetoresistance, multiferroicity, etc. In this chapter, we recompile well-established chemical and structural concepts in pure inorganic perovskites (mainly oxidic perovskites), and extend them to the young family of hybrid organic-inorganic perovskites. Our final goal is to help understanding the relationships among composition, crystal structure and properties in this new family of compounds, for inspiring further the design of novel materials.
