Materials Data on U2Te5 by Materials Project
U2Te5 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one U2Te5 sheet oriented in the (0, 0, 1) direction. there are two inequivalent U5+ sites. In the first U5+ site, U5+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of U–Te bond distances ranging from 3.10–3.24 Å. In the second U5+ site, U5+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of U–Te bond distances ranging from 3.07–3.21 Å. There are five inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to four U5+ atoms to form a mixture of distorted corner and edge-sharing TeU4 trigonal pyramids. In the second Te2- site, Te2- is bonded in a 2-coordinate geometry to two equivalent U5+ atoms. In the third Te2- site, Te2- is bonded in a 2-coordinate geometry to two equivalent U5+ atoms. In the fourth Te2- site, Te2- is bonded in a 6-coordinate geometry to four equivalent U5+ atoms. In the fifth Te2- site, Te2- is bonded to four U5+ atoms to form a mixture of distorted corner and edge-sharing TeU4 trigonal pyramids.
