Materials Data on Dy2PbS4 by Materials Project
Dy2PbS4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Dy3+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are a spread of Dy–S bond distances ranging from 2.75–3.10 Å. Pb2+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are four shorter (2.92 Å) and four longer (3.13 Å) Pb–S bond lengths. S2- is bonded in a 6-coordinate geometry to four equivalent Dy3+ and two equivalent Pb2+ atoms.
