The material structure described by SrCo6O11 crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to six equivalent O(2) and six equivalent O(3) atoms to form distorted SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, edges with six equivalent Co(3)O6 octahedra, edges with three equivalent Co(1)O5 trigonal bipyramids, and faces with six equivalent Co(2)O6 octahedra. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form CoO5 trigonal bipyramids that share corners with six equivalent Co(2)O6 octahedra, corners with six equivalent Co(3)O6 octahedra, and edges with three equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 42-57°. In the second Co site, Co(2) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent Co(3)O6 octahedra, corners with three equivalent Co(1)O5 trigonal bipyramids, faces with three equivalent Sr(1)O12 cuboctahedra, and  a faceface with one Co(2)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. In the third Co site, Co(3) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form CoO6 octahedra that share corners with four equivalent Co(2)O6 octahedra, corners with two equivalent Co(1)O5 trigonal bipyramids, edges with two equivalent Sr(1)O12 cuboctahedra, and edges with four equivalent Co(3)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(1) and three equivalent Co(3) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1), one Co(1), and two equivalent Co(2) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), one Co(2), and two equivalent Co(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
