Influence of oxygen distribution on the Li-ion conductivity in oxy-sulfide glasses – taking a closer look
Li3POxS4-x is synthesised using different sets of precursors, followed by a detailed structural analysis to establish links between the atomic structure and Li-ion conductivity of the materials.
Evolution of Mn–Bi2O3 from the Mn-doped Bi3O4Br electro(pre)catalyst during the oxygen evolution reaction
Bi3O4Br appears to be nearly inactive for the alkaline oxygen evolution reaction while MnII doping into Bi3O4Br alters its electronic structure and makes it OER active. Mn–Bi2O3 evolves as the reactive species from the Mn–Bi3O4Br pre-catalyst.
Growth of submillimeter SrTaO2N single crystals by an NH3-assisted SrCl2 flux method
Cuboid SrTaO2N single crystals with an edge length of 300 μm were grown by an NH3-assisted SrCl2 flux method through evaporation of the flux.
The synthesis and structure–property relation analysis of metal chalcohalide crystals Cs2InPS4X2 (X = Cl, Br) with mixed anions
Two novel metal chalcogenides Cs2InPS4X2 (X = Cl, Br) were successfully synthesized and exhibit large optical band gaps induced by the [InS4X2]7− mixed-anion groups.
RbPb8O4Cl9: the first alkali metal lead oxyhalide with distorted [PbO3Cl3] and [PbOCl5] mixed-anion groups
The first alkali metal lead oxyhalide RbPb8O4Cl9 is designed and synthesized. The compound shows a porous network framework built from unique [PbO3Cl3] and [PbOCl5] mixed-anion groups and [RbCl8] polyhedra.
Low temperature synthesis of barium oxynitridosilicates using BaCN2 and SiO2
Barium oxynitridosilicates were prepared at a low temperature from a mixture of BaCN2 and SiO2. Alkaline earth carbodiimides are a potential nitrogen source for achieving a low-temperature and energy-efficient process for a formation of oxynitrides.
About this collection
Mixed-anion or heteroanion compounds are single-phase materials in which the cations are bonded to more than just one kind of anion. By controlling the anion composition, structural, electric, optical, thermal, electrochemical, and catalytic properties can be effectively modified. Such materials are currently attracting increasing attention as tunable functional materials in applications ranging from electronics and optics to catalysis and energy conversion, and beyond. For various applications and research targets, the mixed-anion materials are synthesised in powder, single-crystal and thin-film forms via diverse synthesis approaches, often supported by advanced theoretical calculations.
This Dalton Transactions Spotlight collection, guest edited by Dalton Transactions Associate Editor Professor Maarit Karppinen (Aalto University, Finland), Professor Simon Clarke (University of Oxford, UK) and Professor Teruki Motohashi (Kanagawa University, Japan), aims to highlight the recent advances in the area of mixed-anion compounds. The collection will cover compounds such as oxynitrides, oxyhalides, mixed chalcogenides and other inorganic compounds incorporating molecular anions (with [SCN]-, [NCN]2-, [BH4]-, [S2]2- etc.) and their diverse applications across energy, catalysis, electronics and more.
Articles will be added to this themed collection as soon as possible after they are published. Please return to this page frequently to see the collection grow!
