Eu(PdBi)2 crystallizes in the tetragonal P4/nmm space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Pd(1), four equivalent Pd(2), four equivalent Bi(1), and four equivalent Bi(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Bi(2) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Bi(2), and four equivalent Bi(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and four equivalent Pd(2) atoms. In the second Bi site, Bi(2) is bonded in a 5-coordinate geometry to four equivalent Eu(1), one Pd(2), and four equivalent Pd(1) atoms.
