| Abstract: | The crystal structure of the U–Ni binary compound previously designated U5Ni7 was studied by X-ray single crystal diffraction showing that the exact formula is U11Ni16. Uranium and nickel atoms are distributed respectively on 5 and 6 Wyckoff positions of the trigonal space group R (n° 148), and the unit-cell dimensions in the hexagonal setting are: a=11.7786(4) Å, c=20.7485(8) Å. Magnetisation measurements indicate itinerant ferromagnetism below Tc=33 K for U11Ni16. |
