Structural Influence of Lone Pairs in GeP N , a Germanium(II) Nitridophosphate.

Owing to their widespread properties, nitridophosphates are of high interest in current research. Explorative high-pressure high-temperature investigations yielded various compounds with stoichiometry MP N (M=Be, Ca, Sr, Ba, Mn, Cd), which are discussed as ultra-hard or luminescent materials, when doped with Eu . Herein, we report the first germanium nitridophosphate, GeP N , synthesized from Ge N and P N at 6 GPa and 800 °C.
