Materials Data on U2Te3 by Materials Project

Abstract

U2Te3 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. there are three inequivalent U3+ sites. In the first U3+ site, U3+ is bonded to eight Te2- atoms to form a mixture of distorted face, edge, and corner-sharing UTe8 hexagonal bipyramids. There are a spread of U–Te bond distances ranging from 3.10–3.26 Å. In the second U3+ site, U3+ is bonded to eight Te2- atoms to form a mixture of distorted face, edge, and corner-sharing UTe8 hexagonal bipyramids. There are a spread of U–Te bond distances ranging from 3.12–3.28 Å. In the third U3+ site, U3+ is bonded to eight Te2- atoms to form a mixture of distorted face, edge, and corner-sharing UTe8 hexagonal bipyramids. There are a spread of U–Te bond distances ranging from 3.12–3.27 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to six U3+ atoms. In the second Te2- site, Te2- is bonded to five U3+ atoms to form a mixture of distorted face, edge, and corner-sharing TeU5 square pyramids. In the third Te2- site, Te2- is bonded to five U3+ atoms to form a mixture of distorted face, edge, and corner-sharing TeU5 square pyramids.
