Oxynitrides are garnering interest because of their variety of novel properties, but their synthesis has typically involved highly reducing conditions that put significant constraints on their composition, structure and properties. Now, the lability of H− in perovskite oxyhydride BaTiO3−xHx has enabled H–/N3– exchange at a lower temperature, yielding a ferroelectric oxynitride BaTiO3−xN2x/3.
