Abstract The crystal structures of the solid solution LaNi5–x In x (x = 0.51) and the ternary compound LaNi9–x In2+x (x = 0.80) have been investigated by single-crystal X-ray data. The LaNi5–x In x phase is isotypic with CaCu5: space group P6/mmm, a = 5.042(2), c = 4.009(1) Å. The crystal structure investigation of LaNi9–x In2+x (x = 0.80) was performed at T = 295 and 100 K: YNi9In2 type, space group P4/mbm, a = 8.3976(3), c = 5.0439(3) Å for T = 295 K and a = 8.3814(2), c = 5.0352(2) Å for T = 100 K. The lanthanum atoms are located on split positions 2a (0 0 0) and 4e (0 0 0.05).

LaNi5-xInx 和 LaNi9-xIn2+x 的单晶结构测定

摘要 通过单晶 X 射线数据研究了固溶体 LaNi5-x In x (x = 0.51) 和三元化合物 LaNi9-x In2+x (x = 0.80) 的晶体结构。LaNi5–x In x 相与 CaCu5 同型:空间群 P6/mmm,a = 5.042(2),c = 4.009(1) Å。LaNi9–x In2+x (x = 0.80) 的晶体结构研究在 T = 295 和 100 K 下进行:YNi9In2 型,空间群 P4/mbm,a = 8.3976(3),c = 5.0439(3) Å T = 295 K 和 a = 8.3814(2), c = 5.0352(2) Å 对于 T = 100 K。镧原子位于分裂位置 2a (0 0 0) 和 4e (0 0 0.05)。
