Abstract
The crystal structures of the solid solution LaNi5–xInx (x = 0.51) and the ternary compound LaNi9–xIn2+x (x = 0.80) have been investigated by single-crystal X-ray data. The LaNi5–xInx phase is isotypic with CaCu5: space group P6/mmm, a = 5.042(2), c = 4.009(1) Å. The crystal structure investigation of LaNi9–xIn2+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).
