Pd5Sr crystallizes in the hexagonal P6/mmm space group. Sr(1) is bonded in a 18-coordinate geometry to six equivalent Pd(1) and twelve equivalent Pd(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1) and six equivalent Pd(2) atoms. In the second Pd site, Pd(2) is bonded to four equivalent Sr(1), four equivalent Pd(1), and four equivalent Pd(2) atoms to form a mixture of edge, face, and corner-sharing PdSr4Pd8 cuboctahedra.
