摘要：

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+. © 1994 Academic Press, Inc.
