CeCu_5-xIn_1+x [x = 0.17 (1)] with the orthorhombic CeCu₆ structure

S. Bobev and E. D. Bauer

Abstract: Large single crystals of the title compound, cerium copper indium, were synthesized from the elements using a eutectic Cu/In mixture as a solvent. CeCu_5-xIn_1+x [x = 0.17 (1)] is a new ternary derivative of the orthorhombic CeCu₆ structure type [space group Pnma (No. 62)]. This result differs from that of Kalychak, Baranyak, Belsky & Dmytrakh [Dopl. Akad. Nauk Ukr. RSR Ser. B (1988). 9, 39-42], who found that CeCu_4.38In_1.62 belongs to a new structure type (space group Pnnm), derived from the parent CeCu₆ compound by doubling the a axis. In the present structure, all the atoms, except one of the Cu species, occupy special positions with mirror symmetry.
