Materials Data on Sn(PbO2)2 by Materials Project

Pb2SnO4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.24–2.86 Å. In the second Pb2+ site, Pb2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.24–2.84 Å. Sn4+ is bonded to six O2- atoms to form edge-sharing SnO6 octahedra. There are two shorter (2.08 Å) and four longer (2.14 Å) Sn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Pb2+ and two equivalent Sn4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Pb2+ and two equivalent Sn4+ atoms. In the third O2- site, O2- is bonded in a trigonal planar geometry to two Pb2+ and one Sn4+ atom.
