Materials Data on UTe2PbO8 by Materials Project

Abstract

UPbTe2O8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. U6+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of U–O bond distances ranging from 1.87–2.68 Å. Pb2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.34–3.08 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 5-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–1.94 Å. In the second Te4+ site, Te4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.31 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one U6+ and two equivalent Pb2+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Pb2+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and one Pb2+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Pb2+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent U6+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Pb2+ and two Te4+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one U6+ and one Te4+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent U6+ and one Te4+ atom.
