Materials Data on Sb8(PbS5)3 by Materials Project
Sb8(PbS5)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Pb–S bond distances ranging from 2.84–3.43 Å. In the second Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Pb–S bond distances ranging from 2.81–3.48 Å. There are four inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded to five S2- atoms to form edge-sharing SbS5 square pyramids. There are a spread of Sb–S bond distances ranging from 2.46–3.10 Å. In the second Sb3+ site, Sb3+ is bonded to five S2- atoms to form distorted edge-sharing SbS5 square pyramids. There are a spread of Sb–S bond distances ranging from 2.52–3.23 Å. In the third Sb3+ site, Sb3+ is bonded in a 5-coordinate geometry to five S2- atoms. There are a spread of Sb–S bond distances ranging from 2.50–3.14 Å. In the fourth Sb3+ site, Sb3+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Sb–S bond distances ranging from 2.45–3.30 Å. There are eight inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to one Pb2+ and four Sb3+ atoms. In the second S2- site, S2- is bonded in a 3-coordinate geometry to two Pb2+ and one Sb3+ atom. In the third S2- site, S2- is bonded in a distorted water-like geometry to two equivalent Pb2+ and two equivalent Sb3+ atoms. In the fourth S2- site, S2- is bonded in a 2-coordinate geometry to two Pb2+ and two Sb3+ atoms. In the fifth S2- site, S2- is bonded to one Pb2+ and four Sb3+ atoms to form distorted edge-sharing SSb4Pb square pyramids. In the sixth S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to one Pb2+ and three Sb3+ atoms. In the seventh S2- site, S2- is bonded in a 2-coordinate geometry to one Pb2+ and two Sb3+ atoms. In the eighth S2- site, S2- is bonded in a distorted water-like geometry to one Pb2+ and two Sb3+ atoms.
