In2Mn2O7 crystallizes in the cubic Fd-3m space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and edges with six equivalent In(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 49°. In(1) is bonded to two equivalent O(2) and six equivalent O(1) atoms to form distorted InO8 hexagonal bipyramids that share edges with six equivalent In(1)O8 hexagonal bipyramids and edges with six equivalent Mn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Mn(1) and two equivalent In(1) atoms. In the second O site, O(2) is bonded to four equivalent In(1) atoms to form corner-sharing OIn4 tetrahedra.
