The novel ternary aluminide URu3Al10
crystallizes in the orthorhombic (Imma
space group) CeRu3Al10 structure type with cell
parameters a = 4.1925(1) Å,
b = 12.4173(5) Å and c = 17.5328(6) Å.
The combination of (i) short Al-Al and Ru-Al interatomic distances and (ii)
long U-Al and U-Ru distances classifies this intermetallic phase as a
“cage”-like one, similarly to other Al-rich U-T-Al (T = transition
metal) compounds.
