The crystal structure described by La4PbSb2 crystallizes in the tetragonal I-42d space group. La(1) is bonded in a 6-coordinate geometry to two equivalent Pb(1) and four equivalent Sb(1) atoms. Pb(1) is bonded to eight equivalent La(1) atoms to form distorted edge-sharing PbLa8 hexagonal bipyramids. Sb(1) is bonded in a 8-coordinate geometry to eight equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
