Gd2Ru2O7 crystallizes in the tetragonal I4_1/amd space group. Gd(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Ru(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Gd(1) and two equivalent Ru(1) atoms to form distorted OGd2Ru2 tetrahedra that share corners with two equivalent O(3)Gd4 tetrahedra, corners with four equivalent O(2)Gd2Ru2 tetrahedra, corners with eight equivalent O(1)Gd2Ru2 tetrahedra,  an edgeedge with one O(3)Gd4 tetrahedra, edges with two equivalent O(1)Gd2Ru2 tetrahedra, and edges with two equivalent O(2)Gd2Ru2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Gd(1) and two equivalent Ru(1) atoms to form distorted OGd2Ru2 tetrahedra that share corners with two equivalent O(3)Gd4 tetrahedra, corners with four equivalent O(2)Gd2Ru2 tetrahedra, corners with eight equivalent O(1)Gd2Ru2 tetrahedra,  an edgeedge with one O(3)Gd4 tetrahedra, and edges with four equivalent O(1)Gd2Ru2 tetrahedra. In the third O site, O(3) is bonded to four equivalent Gd(1) atoms to form OGd4 tetrahedra that share corners with four equivalent O(2)Gd2Ru2 tetrahedra, corners with four equivalent O(3)Gd4 tetrahedra, corners with eight equivalent O(1)Gd2Ru2 tetrahedra, edges with two equivalent O(2)Gd2Ru2 tetrahedra, and edges with four equivalent O(1)Gd2Ru2 tetrahedra.
Gd2Ru2O7 crystallizes in the tetragonal I4_1/amd space group. Gd(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Both Gd(1)-O(2) bond lengths are 2.47 Å. Both Gd(1)-O(3) bond lengths are 2.22 Å. All Gd(1)-O(1) bond lengths are 2.49 Å.
