The material described by SrCo2V2O8 crystallizes in the tetragonal I4_1cd space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-58°. Co(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Co(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and one Co(1) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one V(1), and one Co(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to one Sr(1), one V(1), and two equivalent Co(1) atoms. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and two equivalent Co(1) atoms. is represented by the CIF file [CIF]
