Materials Data on Pr2UTe5 by Materials Project
UPr2Te5 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. U4+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of U–Te bond distances ranging from 3.12–3.30 Å. There are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded to seven Te2- atoms to form a mixture of distorted edge and corner-sharing PrTe7 pentagonal bipyramids. There are a spread of Pr–Te bond distances ranging from 3.14–3.32 Å. In the second Pr3+ site, Pr3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of Pr–Te bond distances ranging from 3.25–3.34 Å. There are six inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 5-coordinate geometry to one U4+ and four Pr3+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to two equivalent U4+ and three Pr3+ atoms. In the third Te2- site, Te2- is bonded in a 5-coordinate geometry to two equivalent U4+ and three Pr3+ atoms. In the fourth Te2- site, Te2- is bonded in a 4-coordinate geometry to one U4+ and three Pr3+ atoms. In the fifth Te2- site, Te2- is bonded in a 6-coordinate geometry to two equivalent U4+ and two equivalent Pr3+ atoms. In the sixth Te2- site, Te2- is bonded in a 4-coordinate geometry to two equivalent U4+ and two equivalent Pr3+ atoms.
