Abstract
Abstract
The solid solutions LaNiIn1–x

x
and CeNiIn1–x

were studied by means of X-ray powder diffraction and EDX analyses in the full concentration range for samples annealed at T = 870 K. The limited solubility of the fourth component in the starting compounds with equiatomic composition, and the limits and the unit cell parameters of the solid solutions have been determined. The crystal structure of CeNiIn0.57Sn0.43 was refined from single-crystal X-ray diffraction data: ZrNiAl-type structure; hexagonal space group P
