Materials Data on PbSeO4 by Materials Project
PbSeO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.59–2.88 Å. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.67–1.69 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one Se6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one Se6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one Se6+ atom.
