The crystal structure described by SrMn2V2O8 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 Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-58°. Mn(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Mn(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 Mn(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 Mn(1) atom. In the third O site, O(2) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and two equivalent Mn(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 Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
