A single crystal of BaCeLuAlSiNO (barium cerium lutetium aluminosilicate nitride oxide) was obtained by heating a mixed powder of BaN, SiN, Al, LuO, and CeO at 2173 K for 1 h under N gas at 0.85 MPa. X-ray single-crystal structure analysis revealed that the title oxynitride is hexa-gonal (lattice constants: = 6.0378 (5) Å, = 9.8133 (9) Å; space group: 6 ) and isostructural with BaYbSiN. (Ba,Ce) and Lu atoms occupy twelvefold and sixfold coordination sites, respectively.
通过在0.85 MPa氮气气氛下,将BaN、SiN、Al、LuO和CeO的混合粉末在2173 K加热1小时,获得了BaCeLuAlSiNO(钡铈镥铝硅酸氮氧化物)单晶。X射线单晶结构分析表明,该氮氧化物为六方晶系(晶格常数: = 6.0378 (5) Å, = 9.8133 (9) Å;空间群:6 ),与BaYbSiN同构。(Ba,Ce)和Lu原子分别占据十二配位和六配位位点。
