Abstract

La2PbTe4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. La3+ is bonded to eight equivalent Te2- atoms to form distorted LaTe8 hexagonal bipyramids that share corners with four equivalent LaTe8 hexagonal bipyramids, corners with four equivalent PbTe8 hexagonal bipyramids, edges with four equivalent LaTe8 hexagonal bipyramids, faces with four equivalent LaTe8 hexagonal bipyramids, and faces with four equivalent PbTe8 hexagonal bipyramids. There are a spread of La–Te bond distances ranging from 3.27–3.46 Å. Pb2+ is bonded to eight equivalent Te2- atoms to form distorted PbTe8 hexagonal bipyramids that share corners with eight equivalent LaTe8 hexagonal bipyramids, edges with four equivalent PbTe8 hexagonal bipyramids, and faces with eight equivalent LaTe8 hexagonal bipyramids. There are four shorter (3.32 Å) and four longer (3.49 Å) Pb–Te bond lengths. Te2- is bonded in a 6-coordinate geometry to four equivalent La3+ and two equivalent Pb2+ atoms.
