The material structure described by SrV6O11 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 SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, edges with six equivalent V(3)O6 octahedra, edges with three equivalent V(1)O5 trigonal bipyramids, and faces with six equivalent V(2)O6 octahedra. There are three inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form VO5 trigonal bipyramids that share corners with six equivalent V(2)O6 octahedra, corners with six equivalent V(3)O6 octahedra, and edges with three equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 43-56°. In the second V site, V(2) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form VO6 octahedra that share corners with six equivalent V(3)O6 octahedra, corners with three equivalent V(1)O5 trigonal bipyramids, faces with three equivalent Sr(1)O12 cuboctahedra, and  a faceface with one V(2)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. In the third V site, V(3) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form VO6 octahedra that share corners with four equivalent V(2)O6 octahedra, corners with two equivalent V(1)O5 trigonal bipyramids, edges with two equivalent Sr(1)O12 cuboctahedra, and edges with four equivalent V(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 V(1) and three equivalent V(3) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1), one V(1), and two equivalent V(2) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), one V(2), and two equivalent V(3) atoms. is represented by the CIF card [CIF]
