The compound described by LiCo5SbO8 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a 4-coordinate geometry to one Co(3), two equivalent Co(2), one O(2), one O(3), and two equivalent O(1) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form CoO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 61°. In the second Co site, Co(2) is bonded in a 7-coordinate geometry to one Li(1), one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the third Co site, Co(3) is bonded in a 7-coordinate geometry to one Li(1), one O(3), one O(4), two equivalent O(1), and two equivalent O(6) atoms. In the fourth Co site, Co(4) is bonded to one O(4), one O(5), and two equivalent O(6) atoms to form CoO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. Sb(1) is bonded to one O(2), one O(5), two equivalent O(1), and two equivalent O(6) atoms to form distorted SbO6 octahedra that share corners with three equivalent Co(1)O4 tetrahedra and corners with three equivalent Co(4)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Li(1), one Co(1), one Co(2), one Co(3), and one Sb(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Li(1), one Co(1), two equivalent Co(2), and one Sb(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Li(1), one Co(1), one Co(3), and two equivalent Co(2) atoms. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Co(3), one Co(4), and two equivalent Co(2) atoms. In the fifth O site, O(5) is bonded in a rectangular see-saw-like geometry to one Co(4), two equivalent Co(2), and one Sb(1) atom. In the sixth O site, O(6) is bonded in a rectangular see-saw-like geometry to one Co(2), one Co(3), one Co(4), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
