Pd5Ba crystallizes in the hexagonal P6/mmm space group. Ba(1) is bonded in a 18-coordinate geometry to six equivalent Pd(2) and twelve equivalent Pd(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent Ba(1), four equivalent Pd(1), and four equivalent Pd(2) atoms to form a mixture of edge, face, and corner-sharing PdBa4Pd8 cuboctahedra. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to three equivalent Ba(1) and six equivalent Pd(1) atoms.
