Eu3Pd2Sn2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 7-coordinate geometry to four equivalent Pd(1), two equivalent Sn(2), and three equivalent Sn(1) atoms. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to four equivalent Pd(1), two equivalent Sn(1), and three equivalent Sn(2) atoms. Pd(1) is bonded in a 10-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), one Pd(1), one Sn(2), and two equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent Eu(2), six equivalent Eu(1), and four equivalent Pd(1) atoms to form a mixture of distorted face, corner, and edge-sharing SnEu8Pd4 cuboctahedra. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to three equivalent Eu(2), four equivalent Eu(1), and two equivalent Pd(1) atoms.

In the first Eu site, Eu(1) is bonded in a 7-coordinate geometry to four equivalent Pd(1), two equivalent Sn(2), and three equivalent Sn(1) atoms. There are a spread of Eu(1)-Pd(1) bond distances ranging from 3.06-3.48 Å. Both Eu(1)-Sn(2) bond lengths are 3.34 Å. There are a spread of Eu(1)-Sn(1) bond distances ranging from 3.53-3.67 Å. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to four equivalent Pd(1), two equivalent Sn(1), and three equivalent Sn(2) atoms. There are two shorter (3.37 Å) and two longer (3.38 Å) Eu(2)-Pd(1) bond lengths. Both Eu(2)-Sn(1) bond lengths are 3.52 Å. There are a spread of Eu(2)-Sn(2) bond distances ranging from 3.26-3.33 Å. Pd(1) is bonded in a 10-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), one Pd(1), one Sn(2), and two equivalent Sn(1) atoms. The Pd(1)-Pd(1) bond length is 2.94 Å.
