The compound described by LiSr2UYbO6 crystallizes in the trigonal R3m space group. Li(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(2)O12 cuboctahedra, faces with four equivalent U(1)O6 octahedra, and faces with four equivalent Yb(1)O6 octahedra. U(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form UO6 octahedra that share corners with six equivalent Yb(1)O6 octahedra and faces with four equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-4°. Yb(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form YbO6 octahedra that share corners with six equivalent U(1)O6 octahedra and faces with four equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-4°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Li(1), one Sr(1), two equivalent Sr(2), one U(1), and one Yb(1) atom. In the second O site, O(2) is bonded in a linear geometry to two equivalent Sr(2), one U(1), and one Yb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
