- Abstract:
-
A new oxynitride, LaZrQ2N, has been synthesized by the reaction of a highly reactive X-ray amorphous La2Zr2O7 precursor with flowing ammonia at between 900 and 1000 °C. The white insulating material crystallizes in the GdFeQ3 distorted perovskite structure type with orthorbombic space group Pnma and with a = 5.875 25(5) Å, b = 8.250 31(7) Å, c = 5.810 08(5) Å, and Z = 4, as determined by neutron powder diffraction. A detailed structural analysis of the isostructural NdTiO2N is also reported: ...
