Materials Data on LiU4P3O20 by Materials Project
LiU4P3O20 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.92–2.18 Å. There are four inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to six O2- atoms to form UO6 octahedra that share a cornercorner with one UO7 pentagonal bipyramid and corners with four PO4 tetrahedra.

There are a spread of U–O bond distances ranging from 1.78–2.54 Å. In the third U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share a cornercorner with one UO6 octahedra, corners with two PO4 tetrahedra, an edgeedge with one UO7 pentagonal bipyramid, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 4°. There are a spread of U–O bond distances ranging from 1.78–2.53 Å. In the fourth U6+ site, 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 1.81–2.30 Å.

The corner-sharing octahedra tilt angles range from 27–41°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two UO6 octahedra, a cornercorner with one UO7 pentagonal bipyramid, and an edgeedge with one UO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 28–33°. There is two shorter (1.53 Å) and two longer (1.57 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 UO6 octahedra and a cornercorner with one UO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 28–33°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. There are twenty inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one U6+, and one P5+ atom. In the third O2- site, O2- is bonded in a linear geometry to two U6+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to one Li1+ and one U6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one U6+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one U6+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one U6+ atom. In the ninth O2- site, O2- is bonded in a linear geometry to one Li1+ and one U6+ atom. In the tenth O2- site, O2- is bonded in a linear geometry to two U6+ atoms. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent U6+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a bent 150 degrees geometry to one U6+ and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a bent 150 degrees geometry to one U6+ and one P5+ atom. In the fourteenth O2- site, O2- is bonded in a single-bond geometry to one U6+ atom.
