We found two ternary intermetallic compounds in the ternary system U-Pd-Al. 
Pd
Al
(
) crystallizes in the hexagonal P6
/mmc structure with lattice parameters 
= 4.3278 and 
= 16.2870 
. Uranium atom occupies one crystallographic site (1/3 2/3 1/4). However, it is randomly replaced by (Al
), leading to a peculiar magnetic ground state. UPd
Al has the same structure as the first neptunium-based superconductor NpPdAl which consists of a stacking of AuCu-type NpPd and Al. UPdAl compound is only stable at hight temperature: annealing treatment at 800 
C decomposes it into hexagonal UPd and PdAl. The stability of AnPdAl is most likely related to the instability of cubic AnPd.
