Materials Data on CsUP3O11 by Materials Project
CsUP3O11 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.12–3.46 Å. U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with five PO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.80–2.45 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one UO7 pentagonal bipyramid and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent UO7 pentagonal bipyramids and corners with two PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.61 Å) P–O bond length. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent UO7 pentagonal bipyramids and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and one P5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Cs1+ and one U6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+, one U6+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+, one U6+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two P5+ atoms. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the eleventh O2- site, O2- is bonded in a single-bond geometry to two equivalent Cs1+ and one U6+ atom.
