The compound described by Ni3Pb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ni(1) is bonded to eight equivalent Ni(1) and four equivalent Pb(1) atoms to form distorted NiNi8Pb4 cuboctahedra that share corners with twelve equivalent Ni(1)Ni8Pb4 cuboctahedra, edges with eight equivalent Pb(1)Ni12 cuboctahedra, edges with sixteen equivalent Ni(1)Ni8Pb4 cuboctahedra, faces with four equivalent Pb(1)Ni12 cuboctahedra, and faces with fourteen equivalent Ni(1)Ni8Pb4 cuboctahedra. Pb(1) is bonded to twelve equivalent Ni(1) atoms to form PbNi12 cuboctahedra that share corners with twelve equivalent Pb(1)Ni12 cuboctahedra, edges with twenty-four equivalent Ni(1)Ni8Pb4 cuboctahedra, faces with six equivalent Pb(1)Ni12 cuboctahedra, and faces with twelve equivalent Ni(1)Ni8Pb4 cuboctahedra. is represented by the CIF file [CIF]
