Abstract
Owing to their widespread properties, nitridophosphates are of high interest in current research. Explorative high-pressure high-temperature investigations yielded various compounds with stoichiometry MP2N4 (M=Be, Ca, Sr, Ba, Mn, Cd), which are discussed as ultra-hard or luminescent materials, when doped with Eu2+. Herein, we report the first germanium nitridophosphate, GeP2N4, synthesized from Ge3N4 and P3N5 at 6 GPa and 800 degrees C. The structure was determined by single-crystal X-ray diffraction and further characterized by energy-dispersive X-ray spectroscopy, density functional theory calculations, IR and NMR spectroscopy. The highly condensed network of PN4-tetrahedra shows a strong structural divergence to other MP2N4 compounds, which is attributed to the stereochemical influence of the lone pair of Ge2+. Thus, the formal exchange of alkaline earth cations with Ge2+ may open access to various compounds with literature-known stoichiometry, however, new structures and properties.
