Materials Data on Lu6UO12 by Materials Project

Lu6U1O12 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. U6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All U–O bond lengths are 2.09 Å. Lu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Lu–O bond distances ranging from 2.17–2.79 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one U6+ and three equivalent Lu3+ atoms. In the second O2- site, O2- is bonded to four equivalent Lu3+ atoms to form a mixture of edge and corner-sharing OLu4 tetrahedra.

Materials Data on LuUO3 by Materials Project

ULuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. U3+ is bonded to twelve equivalent O2- atoms to form UO12 cuboctahedra that share corners with twelve equivalent UO12 cuboctahedra, faces with six equivalent UO12 cuboctahedra, and faces with eight equivalent LuO6 octahedra. All U–O bond lengths are 2.96 Å. Lu3+ is bonded to six equivalent O2- atoms to form LuO6 octahedra that share corners with six equivalent LuO6 octahedra and faces with eight equivalent UO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Lu–O bond lengths are 2.10 Å. O2- is bonded in a distorted linear geometry to four equivalent U3+ and two equivalent Lu3+ atoms.
