MgPd3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Mg(1) is bonded to four equivalent Pd(1), four equivalent Pd(2), and four equivalent Pd(3) atoms to form MgPd12 cuboctahedra that share corners with eight equivalent Mg(1)Pd12 cuboctahedra, edges with four equivalent Mg(1)Pd12 cuboctahedra, edges with eight equivalent Pd(2)Mg4Pd8 cuboctahedra, faces with four equivalent Pd(2)Mg4Pd8 cuboctahedra, and faces with five equivalent Mg(1)Pd12 cuboctahedra. There are three inequivalent Pd sites. In the first Pd site, Pd(3) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Mg(1) and four equivalent Pd(2) atoms. In the second Pd site, Pd(1) is bonded in a distorted square co-planar geometry to four equivalent Mg(1) atoms. In the third Pd site, Pd(2) is bonded to four equivalent Mg(1), four equivalent Pd(2), and four equivalent Pd(3) atoms to form distorted PdMg4Pd8 cuboctahedra that share corners with four equivalent Pd(2)Mg4Pd8 cuboctahedra, edges with eight equivalent Mg(1)Pd12 cuboctahedra, faces with four equivalent Mg(1)Pd12 cuboctahedra, and faces with eight equivalent Pd(2)Mg4Pd8 cuboctahedra.
