Eu(PdSn)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 Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Sn(2), and four equivalent Sn(1) atoms. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and four equivalent Pd(1) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to four equivalent Eu(1), one Pd(1), and four equivalent Pd(2) atoms.
