The material described by PbSn3 crystallizes in the hexagonal P6_3/mmc space group. Pb(1) is bonded to twelve Sn(1,1) atoms to form a mixture of corner and face-sharing PbSn12 cuboctahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 12-coordinate geometry to four equivalent Pb(1) and eight Sn(1,1) atoms. In the second Sn site, Sn(1) is bonded in a 12-coordinate geometry to four equivalent Pb(1) and eight equivalent Sn(1) atoms. is represented by the CIF file [CIF]
