Dy3(Pd10P3)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Pd(1) and twelve equivalent Pd(2) atoms to form distorted DyPd16 tetrahedra that share edges with six equivalent Dy(1)Pd16 tetrahedra and faces with four equivalent Dy(2)P6Pd12 cuboctahedra. In the second Dy site, Dy(2) is bonded to twelve equivalent Pd(2) and six equivalent P(1) atoms to form distorted face-sharing DyP6Pd12 cuboctahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to one Dy(1), six equivalent Pd(2), and three equivalent P(1) atoms. In the second Pd site, Pd(2) is bonded in a 14-coordinate geometry to one Dy(2), two equivalent Dy(1), four equivalent Pd(1), five equivalent Pd(2), and two equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to one Dy(2), four equivalent Pd(1), and four equivalent Pd(2) atoms.

All Dy(1)-Pd(1) bond lengths are 2.83 Å. All Dy(1)-Pd(2) bond lengths are 3.33 Å. In the second Dy site, Dy(2) is bonded to twelve equivalent Pd(2) and six equivalent P(1) atoms to form distorted face-sharing DyP6Pd12 cuboctahedra. All Dy(2)-Pd(2) bond lengths are 2.98 Å. All Dy(2)-P(1) bond lengths are 3.21 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to one Dy(1), six equivalent Pd(2), and three equivalent P(1) atoms. All Pd(1)-Pd(2) bond lengths are 3.02 Å. All Pd(1)-P(1) bond lengths are 2.48 Å. In the second Pd site, Pd(2) is bonded in a 14-coordinate geometry to one Dy(2), two equivalent Dy(1), four equivalent Pd(1), five equivalent Pd(2), and two equivalent P(1) atoms. There is one shorter (2.66 Å) and four longer (2.98 Å) Pd(2)-Pd(2) bond lengths. Both Pd(2)-P(1) bond lengths are 2.37 Å. P(1) is bonded in a 9-coordinate geometry to one Dy(2), four equivalent Pd(1), and four equivalent Pd(2) atoms.
