Abstract
AbstractOwing to their widespread properties, nitridophosphates are of high interest in current research. Explorative high‐pressure high‐temperature investigations yielded various compounds with stoichiometryMP2N4(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 Ge3N4and P3N5at 6 GPa and 800 °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 otherMP2N4compounds, 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.
