Abstract

We report the discovery of a new ternary oxynitride, Na₃WO₃N. Na₃WO₃N is synthesized by exposing a eutectic melt consisting of 1 2Na₂O : 1Na₂WO₄ to a flow of ammonia gas at 695°C. The compound crystallizes in the acentric space group Pmn2₁ with a = 7.2481(3) Å, b = 6.2728(3) Å, and c = 5.6493(2) Å. The structure was determined from synchrotron X-ray powder diffraction data and refined using the Rietveld analysis on neutron powder diffraction data. It is isostructural to the low temperature form of Li₃PO₄ which can be derived from an ordered wurtzite structure-type with all the atoms having tetrahedral coordination. Alternatively, the structure can be described as being “salt-like” consisting of isolated (WO₃N)^-3 tetrahedral polyanions separated by Na⁺.
