The crystal structure described by In3Pb crystallizes in the hexagonal P6_3/mmc space group. In(1) is bonded in a 4-coordinate geometry to four equivalent Pb(1) atoms. Pb(1) is bonded to twelve equivalent In(1) atoms to form a mixture of face and corner-sharing PbIn12 cuboctahedra. is represented by the CIF file [CIF]
