Materials Data on PbSO3 by Materials Project
PbSO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.57–3.10 Å. S4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.54 Å) and two longer (1.56 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Pb2+ and one S4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Pb2+ and one S4+ atom.
