The material described by Mg2WAgO6 is Ilmenite-derived structured and crystallizes in the triclinic P1 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted MgO6 octahedra that share corners with three equivalent W(1)O6 octahedra, corners with six equivalent Mg(2)O6 octahedra, and  a faceface with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-56°. In the second Mg site, Mg(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted MgO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra and edges with three equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-56°. W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form WO6 octahedra that share corners with three equivalent Mg(1)O6 octahedra, edges with three equivalent Mg(2)O6 octahedra, and  a faceface with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-54°. Ag(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Ag(1) atom. In the second O site, O(2) is bonded to one Mg(1), one Mg(2), one W(1), and one Ag(1) atom to form a mixture of distorted corner and edge-sharing OMg2AgW trigonal pyramids. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Ag(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Mg(1), one Mg(2), one W(1), and one Ag(1) atom. In the fifth O site, O(5) is bonded to one Mg(1), one Mg(2), one W(1), and one Ag(1) atom to form a mixture of distorted corner and edge-sharing OMg2AgW trigonal pyramids. In the sixth O site, O(6) is bonded to one Mg(1), one Mg(2), one W(1), and one Ag(1) atom to form a mixture of distorted corner and edge-sharing OMg2AgW trigonal pyramids. is represented by the CIF file [CIF]
