Abstract

The compound LaNi₄Co is isostructural with LaNi₅. The distribution of the Co atoms in the 2c and 3g special positions of the space group D_6h¹-P6/mmm is not random. Deuterisation yields LaNi₄CoD₄ with structure that belongs to the orthorhombic space group D_2h¹⁹-Cmmm. The deuterium atoms occupy the 4e and 4h special position of this symmetry. The reduced deuterium content in LaNi₄CoD₄ as compared with that in LaNi₅D ₆ is consistent with geometrical considerations and the different symmetries.
