Structural Influence of Lone Pairs in GeP(2)N(4), 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(2)N(4) (M=Be, Ca, Sr, Ba, Mn, Cd), which are discussed as ultra‐hard or luminescent materials, w...

description 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(2)N(4) (M=Be, Ca, Sr, Ba, Mn, Cd), which are discussed as ultra‐hard or luminescent materials, when doped with Eu(2+). Herein, we report the first germanium nitridophosphate, GeP(2)N(4), synthesized from Ge(3)N(4) and P(3)N(5) at 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 PN(4)‐tetrahedra shows a strong structural divergence to other MP(2)N(4) compounds, which is attributed to the stereochemical influence of the lone pair of Ge(2+). Thus, the formal exchange of alkaline earth cations with Ge(2+) may open access to various compounds with literature‐known stoichiometry, however, new structures and properties.
