Pd3Sn crystallizes in the trigonal R-3m space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 3-coordinate geometry to three equivalent Pd(2) and three equivalent Sn(1) atoms. In the second Pd site, Pd(2) is bonded to six equivalent Pd(1) and six equivalent Pd(2) atoms to form a mixture of corner, face, and edge-sharing PdPd12 cuboctahedra. Sn(1) is bonded in a 6-coordinate geometry to six equivalent Pd(1) atoms.
