Crystalline Nitridophosphates by Ammonothermal Synthesis

Nitridophosphates are a well-studied class of compounds with high structural diversity. However, their synthesis is quite challenging, particularly due to the limited thermal stability of starting materials like P3N5. Typically, it requires even high-pressure techniques (e.g. multianvil) in most cases. Herein, we establish the ammonothermal method as a versatile synthetic tool to access nitridophosphates with different degrees of condensation. α-Li10P4N10, β-Li10P4N10, Li18P6N16, Ca2PN3, SrP8N14, and LiPN2 were synthesized in supercritical NH3 at temperatures and pressures up to 1070 K and 200 MPa employing ammonobasic conditions. The products were analyzed by powder X-ray diffraction, energy dispersive X-ray spectroscopy, and FTIR spectroscopy. Moreover, we established red phosphorus as a starting material for nitridophosphate synthesis instead of commonly used and not readily available precursors, such as P3N5. This opens a promising preparative access to the emerging compound class of nitridophosphates.

Electronic and ionic conductivity in alkaline earth diazenides M AEN2 (MAE = Ca, Sr, Ba) and in Li 2N2

Electrical conductivity measurements of alkaline earth diazenides SrN 2 and BaN2 revealed temperature-dependent metal-like behavior. As CaN2 is isotypic with SrN2 its electronic properties are supposed to show similar characteristics. For the alkali diazenide Li2N2, the corresponding measurement shows not only the typical characteristics of metallic materials but also an unexpected rise in electrical conductivity above 250 K, which is consistent with an ionic contribution. This interpretation is further corroborated by static 6Li and 7Li nuclear magnetic resonance measurements (NMR) of the spin-lattice relaxation time (T1) over an extended temperature range from 50 to 425 K. We observe a constant Heitler-Teller product (T 1T) as expected for metals at low temperatures and a maximum in the temperature-dependent relaxation rates, which reflects the suggested ionic conductivity. A topological structural analysis indicates possible 3D ion migration pathways between two of the three crystallographic independent Li positions. A crude estimate of temperature-dependent self-diffusion coefficients D(T) of the lithium motion classifies Li2N2 as a mixed electronic/ionic conductor.
