Materials Data on Cs2UP2O9 by Materials Project
Abstract
Cs2UP2O9 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Cs–O bond distances ranging from 3.14–3.47 Å. In the second Cs1+ site, Cs1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Cs–O bond distances ranging from 3.07–3.74 Å. U6+ is bonded to six O2- atoms to form UO6 octahedra that share corners with four PO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.82–2.31 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent UO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 41°. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent UO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. There aremore »

In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Cs1+ and two equivalent P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Cs1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two Cs1+, one U6+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Cs1+ and two equivalent P5+ atoms.
