Abstract
The binary Laves phases ScCo2 (MgCu2 type) and TaCo2 (MgNi2 type) show solid solutions with indium; synthesis of Sc1−xInxCo2 samples in sealed tantalum tubes results in tantalum uptake from the container material. Ternary and quaternary samples of these Laves phases were synthesized by direct reactions of the elements followed by different annealing sequences in induction or muffle furnaces. The following structures were refined from single-crystal X-ray diffractometer data: Sc0.08In0.19Ta0.73Co2, Sc0.26In0.5Ta0.24Co2, Sc0.25In0.34Ta0.41Co2 (all MgCu4Sn type, F
