Zn8[P12N24]O2 – ein Nitridophosphat‐oxid mit Sodalith‐Struktur

Abstract

AbstractZn8P12N24O2 – a Nitridophosphate Oxide with Sodalite StructureThe reaction between zinc metal and phosphorus nitride imide PN(NH) was investigated. Surprisingly, no Zn6P12N24 was formed as assumed in former investigations but phase pure Zn8[P12N24]O2 ( (Nr. 217), a = 8.2422(2) Å; Z = 1) was obtained due to contamination by a small amount of oxygen. The existence of Zn8[P12N24]O2 was formerly supposed, but neither its crystal structure nor its exact composition have been unequivocally reported so far. The stoichiometric formula was deducted from elemental analyses, XANES spectroscopy at the phosphorus K‐threshold and IR‐spectroscopy using the crystallographic results of electron diffraction, X‐ray powder diffraction and solid‐state NMR spectroscopy. Zn8[P12N24]O2 adopts the sodalite structure type and is thus isotypic with Zn8[P12N24]X2 with X = S, Se, Te and Zn8[B12O24]O2.
