Pd2Zn crystallizes in the tetragonal P4/mmm space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to four equivalent Pd(3) and four equivalent Zn(1) atoms. In the second Pd site, Pd(2) is bonded in a body-centered cubic geometry to eight equivalent Zn(1) atoms. In the third Pd site, Pd(3) is bonded to four equivalent Pd(3) and eight equivalent Pd(1) atoms to form a mixture of corner and face-sharing PdPd12 cuboctahedra. Zn(1) is bonded in a body-centered cubic geometry to four equivalent Pd(1) and four equivalent Pd(2) atoms.
