Materials Data on Cs2U3(TeO7)2 by Materials Project
Cs2U3(TeO7)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cs–O bond distances ranging from 3.05–3.36 Å. There are two inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share a cornercorner with one UO6 octahedra, an edgeedge with one UO6 octahedra, and an edgeedge with one UO7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 47°. There are a spread of U–O bond distances ranging from 1.84–2.51 Å. In the second U6+ site, U6+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing UO6 octahedra. There are a spread of U–O bond distances ranging from 1.85–2.34 Å. Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–1.91 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one U6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two U6+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+ and one U6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one U6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Cs1+, one U6+, and one Te4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to three U6+ atoms. In the seventh O2- site, O2- is bonded in a linear geometry to one U6+ and one Te4+ atom.
