Materials Data on Tb2PbS4 by Materials Project
Tb2PbS4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Tb3+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are a spread of Tb–S bond distances ranging from 2.77–3.09 Å. Pb2+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are four shorter (2.93 Å) and four longer (3.12 Å) Pb–S bond lengths. S2- is bonded in a 6-coordinate geometry to four equivalent Tb3+ and two equivalent Pb2+ atoms.
