Popis:	The ternary alloys UCo 4.5 In 0.5 and UCo 4 In were synthesized and characterized by X-ray diffraction at room temperature. They crystallizes in the FCC-based MgSnCu 4 -type structure, closely related to the AuBe 5 -type structure of the UT 5 compounds (T=Ni, Cu, Pt), otherwise not found in binary U–Co phases around the Co/U atomic ratio equal to 5. The lattice parameter of the supposedly terminal compound UCo 4 In is 694.5±0.5 pm. This value locates in the range of those of isostructural compounds. Measurements of the magnetization, performed for the two above compositions in the wide range of temperatures 1.7–500 K, indicate weak ferrimagnetic behavior with approximate Curie temperatures of T c =430 and 350 K, respectively. The electrical resistivity measured in the range 4.2–300 K confirms their metallic character.
