The material described by Gd2InSbO7 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(2), two equivalent O(4), and four equivalent O(3) atoms to form distorted GdO8 hexagonal bipyramids that share edges with two equivalent Gd(1)O8 hexagonal bipyramids, edges with two equivalent In(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. In the second Gd site, Gd(2) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(4), and four equivalent O(3) atoms. In(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form InO6 octahedra that share corners with two equivalent In(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 53-61°. Sb(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent In(1)O6 octahedra, and edges with four equivalent Gd(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 40-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Gd(2) and two equivalent In(1) atoms to form OGd2In2 tetrahedra that share corners with two equivalent O(4)Gd4 tetrahedra, corners with four equivalent O(1)Gd2In2 tetrahedra, corners with eight equivalent O(3)Gd2InSb tetrahedra,  an edgeedge with one O(4)Gd4 tetrahedra, and edges with four equivalent O(3)Gd2InSb tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Gd(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded to one Gd(1), one Gd(2), one In(1), and one Sb(1) atom to form distorted OGd2InSb tetrahedra that share corners with two equivalent O(1)Gd2In2 tetrahedra, corners with two equivalent O(4)Gd4 tetrahedra, corners with eight equivalent O(3)Gd2InSb tetrahedra,  an edgeedge with one O(1)Gd2In2 tetrahedra,  an edgeedge with one O(4)Gd4 tetrahedra, and edges with two equivalent O(3)Gd2InSb tetrahedra. In the fourth O site, O(4) is bonded to two equivalent Gd(1) and two equivalent Gd(2) atoms to form OGd4 tetrahedra that share corners with two equivalent O(1)Gd2In2 tetrahedra, corners with four equivalent O(4)Gd4 tetrahedra, corners with eight equivalent O(3)Gd2InSb tetrahedra,  an edgeedge with one O(1)Gd2In2 tetrahedra, and edges with four equivalent O(3)Gd2InSb tetrahedra. is represented by the CIF file [CIF]
