Materials Data on TePb2O5 by Materials Project

Abstract

Pb2TeO5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Pb2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.40–3.14 Å. Te6+ is bonded to six O2- atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of Te–O bond distances ranging from 1.93–2.06 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Pb2+ and one Te6+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Pb2+ and one Te6+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Pb2+ and two equivalent Te6+ atoms.
