Materials Data on Sb3Pb by Materials Project
PbSb3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pb2+ is bonded to twelve equivalent Sb+0.67- atoms to form a mixture of face and corner-sharing PbSb12 cuboctahedra. There are six shorter (3.39 Å) and six longer (3.55 Å) Pb–Sb bond lengths. Sb+0.67- is bonded in a 12-coordinate geometry to four equivalent Pb2+ and eight equivalent Sb+0.67- atoms. There are a spread of Sb–Sb bond distances ranging from 3.28–3.49 Å.
