La3Zn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. La(1) is bonded to eight equivalent La(1) and four equivalent Zn(1) atoms to form distorted LaLa8Zn4 cuboctahedra that share corners with twelve equivalent La(1)La8Zn4 cuboctahedra, edges with eight equivalent Zn(1)La12 cuboctahedra, edges with sixteen equivalent La(1)La8Zn4 cuboctahedra, faces with four equivalent Zn(1)La12 cuboctahedra, and faces with fourteen equivalent La(1)La8Zn4 cuboctahedra. Zn(1) is bonded to twelve equivalent La(1) atoms to form ZnLa12 cuboctahedra that share corners with twelve equivalent Zn(1)La12 cuboctahedra, edges with twenty-four equivalent La(1)La8Zn4 cuboctahedra, faces with six equivalent Zn(1)La12 cuboctahedra, and faces with twelve equivalent La(1)La8Zn4 cuboctahedra.
