Hochdruck-Synthese, Kristallstruktur und Eigenschaften von NaPN2

Abstract: Inhaltsu È bersicht. Das Nitridophosphat NaPN 2 wurde ro È ntgenographisch phasenrein durch Umsetzung von NaN 3 und P 3 N 5 in einer Multianvil-Apparatur bei 3 GPa und 1000°C dargestellt. Die Verbindung kristallisiert in einer Variante der Chalkopyrit-Struktur und ist isotyp zu LiPN 2 . Die Kristallstruktur konnte durch Rietveld-Methoden vollsta È ndig verfeinert werden (I 4 2d, a = 497,21(2), c = 697,60(3) pm, Z = 4, 36 beobachtete Reflexe, R p = 0,0502, wR p = 0,0649, R F = 0,0788). High-Pressure Synthesis, … Show more

“…Moreover,a ni ncreased reactivity might be ascribed to the azides because of the in situ formation of the metal nitrides, similar to the use of carbonates for oxide synthesis. [30,31,[65][66][67] By using ammonium azide NH 4 N 3 ,anitridic clathrate P 4 N 4 (NH) 4 (NH 3 )w ith trapped ammonia molecules has been obtained [Eq. These are especially interesting as the element combination PN 2 À is isoelectronic to SiO 2 and often forms (alumo)silicate-related frameworks.…”

“…Solche Raumnetze sind von besonderem Interesse,d ad ie Elementkombination PN 2 À isoelektronisch zu SiO 2 ist und daher den (Alumo)silicaten verwandte Strukturen gebildet werden.

“…[12,13,32] BeP 2 N 4 , which has recently been described, is another example with high hardness, and an even denser and harder high-pressure polymorph has been predicted. [36][37][38][39][40][41][42][43][44][45][46][47][48] With respect to the intriguing properties that can be expected (e.g., color, magnetism, electronic properties), access to transition-metal nitridophosphates remains a challenge. Besides Zn 6 P 12 N 24 , which later was proved to be the quaternary compound Zn 8 P 12 N 24 O 2 , [33,34] and Mn 2 PN 3 , which crystallizes in a wurtzite-like structure, [35] only main-group-element-containing ternary nitridophosphates have been described.…”
