Lu-atom-ordered oxonitridoaluminosilicate Ba_0.9Ce_0.1LuAl_0.2Si_3.8N_6.9O_0.1.

ABSTRACT: A single crystal of Ba_0.9Ce_0.1LuAl_0.2Si_3.8N_6.9O_0.1 (barium cerium lutetium aluminosilicate nitride oxide) was obtained by heating a mixed powder of Ba₃N₂, Si₃N₄, Al, Lu₂O₃, and CeO₂ at 2173 K for 1 h under N₂ gas at 0.85 MPa. X-ray single-crystal structure analysis revealed that the title oxynitride is hexa-gonal (lattice constants: a = 6.0378 (5) Å, c = 9.8133 (9) Å; space group: P6₃ mc) and isostructural with BaYbSi₄N₇. (Ba,Ce) and Lu atoms occupy twelvefold and sixfold coordination sites, respectively.
