The material described by Ce2(Pd7Si2)3 crystallizes in the cubic Fm-3m space group. Ce(1) is bonded in a distorted tetrahedral geometry to four equivalent Pd(2) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to twelve equivalent Pd(3) and six equivalent Si(1) atoms to form distorted corner-sharing PdSi6Pd12 cuboctahedra. In the second Pd site, Pd(2) is bonded to one Ce(1) and three equivalent Si(1) atoms to form PdCeSi3 tetrahedra that share corners with three equivalent Pd(1)Si6Pd12 cuboctahedra, corners with six equivalent Pd(2)CeSi3 tetrahedra, and edges with three equivalent Pd(2)CeSi3 tetrahedra. In the third Pd site, Pd(3) is bonded in a distorted bent 150 degrees geometry to one Pd(1) and two equivalent Si(1) atoms. Si(1) is bonded in a 8-coordinate geometry to one Pd(1), four equivalent Pd(2), and four equivalent Pd(3) atoms. is represented by the CIF card [CIF]
