Abstract

Pb9Sb8S21 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are five inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to seven S2- atoms to form distorted PbS7 pentagonal bipyramids that share a cornercorner with one PbS7 pentagonal bipyramid, corners with two equivalent PbS6 pentagonal pyramids, corners with two SbS5 square pyramids, an edgeedge with one PbS6 octahedra, an edgeedge with one PbS6 pentagonal pyramid, and edges with two SbS5 square pyramids. There are a spread of Pb–S bond distances ranging from 2.89–3.45 Å. In the second Pb2+ site, Pb2+ is bonded to six S2- atoms to form distorted PbS6 pentagonal pyramids that share a cornercorner with one PbS6 octahedra, corners with two equivalent PbS7 pentagonal bipyramids, a cornercorner with one SbS5 square pyramid, an edgeedge with one PbS6 octahedra, an edgeedge with one PbS7 pentagonal bipyramid, and edges with four SbS5 square pyramids.

In the fourth Sb3+ site, Sb3+ is bonded in a distorted see-saw-like geometry to four S2- atoms. There are a spread of Sb–S bond distances ranging from 2.45–3.24 Å. There are eleven inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to three Pb2+ and three Sb3+ atoms. In the second S2- site, S2- is bonded in a 1-coordinate geometry to two Pb2+ and one Sb3+ atom.
