The crystal structure described by Gd2ReO5 crystallizes in the tetragonal P4/n space group. Gd(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), three equivalent O(3), and three equivalent O(4) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted square co-planar geometry to four equivalent O(3) atoms. In the second Re site, Re(2) is bonded in a distorted square co-planar geometry to four equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Gd(1) atoms to form OGd4 tetrahedra that share corners with twelve equivalent O(4)Gd3Re tetrahedra and edges with two equivalent O(2)Gd4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Gd(1) atoms to form OGd4 tetrahedra that share corners with four equivalent O(4)Gd3Re tetrahedra, edges with two equivalent O(1)Gd4 tetrahedra, and edges with four equivalent O(4)Gd3Re tetrahedra. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent Gd(1) and one Re(1) atom. In the fourth O site, O(4) is bonded to three equivalent Gd(1) and one Re(2) atom to form distorted OGd3Re tetrahedra that share  a cornercorner with one O(2)Gd4 tetrahedra, corners with three equivalent O(4)Gd3Re tetrahedra, corners with three equivalent O(1)Gd4 tetrahedra,  an edgeedge with one O(2)Gd4 tetrahedra, and edges with three equivalent O(4)Gd3Re tetrahedra. is represented by the CIF card [CIF]
