The material structure described by SnPb crystallizes in the monoclinic Pm space group. Pb(1) is bonded to six equivalent Pb(1) and six equivalent Sn(1) atoms to form distorted PbSn6Pb6 cuboctahedra that share corners with twelve equivalent Sn(1)Pb6 cuboctahedra, corners with eighteen equivalent Pb(1)Sn6Pb6 cuboctahedra, edges with six equivalent Pb(1)Sn6Pb6 cuboctahedra, edges with twelve equivalent Sn(1)Pb6 cuboctahedra, and faces with eight equivalent Pb(1)Sn6Pb6 cuboctahedra. Sn(1) is bonded to six equivalent Pb(1) atoms to form distorted SnPb6 cuboctahedra that share corners with twelve equivalent Pb(1)Sn6Pb6 cuboctahedra, corners with twelve equivalent Sn(1)Pb6 cuboctahedra, edges with six equivalent Sn(1)Pb6 cuboctahedra, edges with twelve equivalent Pb(1)Sn6Pb6 cuboctahedra, and faces with two equivalent Sn(1)Pb6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
