✦ Synopsis

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 5Àx In 1+x [x = 0.17 ( 1)] is a new ternary derivative of the orthorhombic CeCu 6 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 4.38 In 1.62 belongs to a new structure type (space group Pnnm), derived from the parent CeCu 6 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.

A ball-and-stick view down the b axis of the PrCu 5Àx In 1+x structure. In1 and In2/Cu2 are shown as purple open circles, and Cu3, Cu4 and Cu5 are drawn as shaded orange circles. Pr atoms are shown as isolated (not connected) hatched gray circles for clarity. The unit cell is outlined.
