Combination of Ambient and High-Temperature Beryllium Nitride Motifs in WBeN and WBeN.

Compounds of transition metals and beryllium have a wide range of applications, from everyday tools to high tech applications. Remarkably, no single ternary beryllium nitride with a transition metal is known. Here, we report on the synthesis and properties of the first transition metal nitridoberyllates, namely WBeN and WBeN.

High-pressure synthesis of Ruddlesden-Popper nitrides.

Layered perovskites with Ruddlesden-Popper-type structures are fundamentally important for low-dimensional properties, for example, photovoltaic hybrid iodides and superconducting copper oxides. Many such halides and oxides are known, but analogous nitrides are difficult to stabilize due to the high cation oxidation states required to balance the anion charges. Here we report the high-pressure synthesis of three single-layer Ruddlesden-Popper (KNiF type) nitrides-PrReN, NdReN and CeTaN-along with their structural characterization and properties.
