Front Cover: Synthesis and Characterization of A3[ReO4][ReO3N] and A′2[ReO3N] (A = Rb, Cs; A′ = K, Cs) (Eur. J. Inorg. Chem. 17/2025)

Abstract

The Front Cover illustrates how the oxygen atoms in [ReO₄]^– can be replaced by nitrogen atoms upon controlled addition of NH₄⁺ as a nitrogen source. From the reaction of NH₄[ReO₄] in an alkali metal hydroxide flux, Rb₃[ReO₄][ReO₃N] and Cs₃[ReO₄][ReO₃N] could be synthesized. In order to obtain monoanionic products, namely K₂[ReO₃N] and Cs₂[ReO₃N], NH₄Cl was added to the corresponding alkali metal hydroxide as an additional nitrogen source.
