The material described by Mn2Sb2O7 crystallizes in the cubic Fd-3m space group. Mn(1) is bonded to two equivalent O(1) and six equivalent O(2) atoms to form distorted MnO8 hexagonal bipyramids that share edges with six equivalent Mn(1)O8 hexagonal bipyramids and edges with six equivalent Sb(1)O6 octahedra. Sb(1) is bonded to six equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and edges with six equivalent Mn(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Mn(1) atoms to form OMn4 tetrahedra that share corners with four equivalent O(1)Mn4 tetrahedra, corners with twelve equivalent O(2)Mn2Sb2 tetrahedra, and edges with six equivalent O(2)Mn2Sb2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Mn(1) and two equivalent Sb(1) atoms to form distorted OMn2Sb2 tetrahedra that share corners with two equivalent O(1)Mn4 tetrahedra, corners with twelve equivalent O(2)Mn2Sb2 tetrahedra,  an edgeedge with one O(1)Mn4 tetrahedra, and edges with four equivalent O(2)Mn2Sb2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
