Sr2LiReO6 crystallizes in the tetragonal I4/m space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Re(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-18°. Sr(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Li(1)O6 octahedra, and faces with four equivalent Re(1)O6 octahedra. Re(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ReO6 octahedra that share corners with six equivalent Li(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-18°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), four equivalent Sr(1), and one Re(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Li(1), four equivalent Sr(1), and one Re(1) atom.
Sr2LiReO6 crystallizes in the tetragonal I4/m space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Re(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-18°. Both Li(1)-O(2) bond lengths are 2.12 Å. All Li(1)-O(1) bond lengths are 2.12 Å. Sr(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Li(1)O6 octahedra, and faces with four equivalent Re(1)O6 octahedra.
