The structure described by Tb2MnSbO7 crystallizes in the orthorhombic Imma space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to two equivalent O(1), two equivalent O(2), and four equivalent O(4) atoms to form distorted TbO8 hexagonal bipyramids that share edges with two equivalent Tb(1)O8 hexagonal bipyramids, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. In the second Tb site, Tb(2) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(4) atoms.
