The material described by La4SnBi2 crystallizes in the tetragonal I-42d space group. La(1) is bonded in a 6-coordinate geometry to two equivalent Sn(1) and four equivalent Bi(1) atoms. Sn(1) is bonded to eight equivalent La(1) atoms to form distorted edge-sharing SnLa8 hexagonal bipyramids. Bi(1) is bonded in a 8-coordinate geometry to eight equivalent La(1) atoms. is represented by the CIF file [CIF]
