The compound described by AgGdW2O8 crystallizes in the monoclinic C2/m space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form distorted edge-sharing WO6 octahedra. In the second W site, W(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted edge-sharing WO6 octahedra. Ag(1) is bonded in a 6-coordinate geometry to one O(4), one O(5), two equivalent O(2), and two equivalent O(3) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Gd(1), one W(1), and one W(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Gd(1), one W(2), and one Ag(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Gd(1), one W(1), and one Ag(1) atom. In the fourth O site, O(4) is bonded to one W(1), two equivalent W(2), and one Ag(1) atom to form OAgW3 tetrahedra that share corners with two equivalent O(5)Gd2AgW tetrahedra and  an edgeedge with one O(4)AgW3 tetrahedra. In the fifth O site, O(5) is bonded to two equivalent Gd(1), one W(1), and one Ag(1) atom to form distorted OGd2AgW tetrahedra that share corners with two equivalent O(4)AgW3 tetrahedra and  an edgeedge with one O(5)Gd2AgW tetrahedra. is represented by the CIF file [CIF]
