Materials Data on Pb2SO5 by Materials Project
Pb2(SO4)O crystallizes in the monoclinic C2/m 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 O2- atoms. There are a spread of Pb–O bond distances ranging from 2.31–3.17 Å. In the second Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.36–3.17 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.49 Å) and three longer (1.50 Å) S–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to four Pb2+ atoms to form edge-sharing OPb4 tetrahedra. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one S6+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to three Pb2+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one S6+ atom.
