The crystal structure described by Gd2MnSbO7 crystallizes in the orthorhombic Imma space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to two equivalent O(1), two equivalent O(3), and four equivalent O(4) atoms to form distorted GdO8 hexagonal bipyramids that share edges with two equivalent Gd(1)O8 hexagonal bipyramids, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. In the second Gd site, Gd(2) is bonded in a distorted body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(4) atoms. Mn(1) is bonded to two equivalent O(2) and four equivalent O(4) atoms to form MnO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and edges with two equivalent Gd(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 50-52°. Sb(1) is bonded to two equivalent O(3) and four equivalent O(4) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent Mn(1)O6 octahedra, and edges with four equivalent Gd(1)O8 hexagonal bipyramids.
