The crystal structure described by Pr3(Pd10Si3)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Pd(1) and twelve equivalent Pd(2) atoms to form distorted PrPd16 tetrahedra that share edges with six equivalent Pr(1)Pd16 tetrahedra and faces with four equivalent Pr(2)Pd12 cuboctahedra. In the second Pr site, Pr(2) is bonded to twelve equivalent Pd(2) atoms to form distorted face-sharing PrPd12 cuboctahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to one Pr(1) and three equivalent Si(1) atoms to form a mixture of corner and edge-sharing PdPrSi3 tetrahedra. In the second Pd site, Pd(2) is bonded in a 2-coordinate geometry to one Pr(2), two equivalent Pr(1), and two equivalent Si(1) atoms. Si(1) is bonded in a 8-coordinate geometry to four equivalent Pd(1) and four equivalent Pd(2) atoms. is represented by the CIF card [CIF]
