The crystal structure described by SmAg(WO4)2 crystallizes in the monoclinic C2/m space group. Sm(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 in a distorted octahedral geometry to one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms. In the second W site, W(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. 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 Sm(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 Sm(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 Sm(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)Sm2AgW tetrahedra and  an edgeedge with one O(4)AgW3 tetrahedra. In the fifth O site, O(5) is bonded to two equivalent Sm(1), one W(1), and one Ag(1) atom to form distorted OSm2AgW tetrahedra that share corners with two equivalent O(4)AgW3 tetrahedra and  an edgeedge with one O(5)Sm2AgW tetrahedra. is represented by the CIF file [CIF]
