Materials Data on UTeO5 by Materials Project

Abstract

UTeO5 crystallizes in the orthorhombic Pbcm space group. The structure is two-dimensional and consists of one UTeO5 sheet oriented in the (1, 0, 0) direction. U6+ is bonded to seven O2- atoms to form distorted edge-sharing UO7 pentagonal bipyramids. There are a spread of U–O bond distances ranging from 1.81–2.44 Å. Te4+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are two shorter (1.93 Å) and two longer (2.07 Å) Te–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one U6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one U6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one U6+ and two equivalent Te4+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent U6+ and one Te4+ atom.
