PdZn3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Pd(1) is bonded to four equivalent Zn(2) and eight equivalent Zn(1) atoms to form PdZn12 cuboctahedra that share corners with four equivalent Pd(1)Zn12 cuboctahedra, edges with eight equivalent Pd(1)Zn12 cuboctahedra, edges with sixteen equivalent Zn(1)Zn8Pd4 cuboctahedra, faces with four equivalent Pd(1)Zn12 cuboctahedra, and faces with eight equivalent Zn(1)Zn8Pd4 cuboctahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to four equivalent Pd(1), four equivalent Zn(1), and four equivalent Zn(2) atoms to form distorted ZnZn8Pd4 cuboctahedra that share corners with twelve equivalent Zn(1)Zn8Pd4 cuboctahedra, edges with eight equivalent Pd(1)Zn12 cuboctahedra, edges with eight equivalent Zn(1)Zn8Pd4 cuboctahedra, faces with four equivalent Pd(1)Zn12 cuboctahedra, and faces with ten equivalent Zn(1)Zn8Pd4 cuboctahedra. In the second Zn site, Zn(2) is bonded in a distorted square co-planar geometry to four equivalent Pd(1) and eight equivalent Zn(1) atoms.
