Materials Data on Pb(SeO3)2 by Materials Project

Abstract

Pb(SeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Pb2+ is bonded in an octahedral geometry to six O2- atoms. There are two shorter (2.20 Å) and four longer (2.22 Å) Pb–O bond lengths. Se5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.73–1.75 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Pb2+ and one Se5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Pb2+ and one Se5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Pb2+ and one Se5+ atom.
