The material described by La2PbTe4 crystallizes in the tetragonal I-42d space group. La(1) is bonded to eight equivalent Te(1) atoms to form a mixture of distorted edge, face, and corner-sharing LaTe8 hexagonal bipyramids. Pb(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. Te(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
