The material structure described by MgMo(WO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(1), one O(4), one O(5), and one O(6) atom to form MgO4 tetrahedra that share corners with two equivalent W(1)O6 octahedra, corners with two equivalent Mo(1)O6 octahedra, and corners with three equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-73°. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(7), and one O(8) atom to form distorted WO6 octahedra that share  a cornercorner with one Mo(1)O6 octahedra, corners with two equivalent Mg(1)O4 tetrahedra, edges with two equivalent W(2)O6 octahedra, and edges with two equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles are 27°. In the second W site, W(2) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form distorted WO6 octahedra that share  a cornercorner with one Mo(1)O6 octahedra, corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent W(1)O6 octahedra, and edges with two equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles are 26°. Mo(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(7), and one O(8) atom to form MoO6 octahedra that share  a cornercorner with one W(1)O6 octahedra,  a cornercorner with one W(2)O6 octahedra, corners with two equivalent Mg(1)O4 tetrahedra, edges with two equivalent W(1)O6 octahedra, and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 26-27°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Mg(1) and one W(1) atom. In the second O site, O(2) is bonded in a water-like geometry to one W(1) and one Mo(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one W(1), one W(2), and one Mo(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one W(1), one W(2), and one Mo(1) atom. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to one Mg(1), one W(2), and one Mo(1) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Mg(1) and one W(2) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one Mo(1) atom. In the eighth O site, O(8) is bonded in a trigonal non-coplanar geometry to one W(1), one W(2), and one Mo(1) atom. is represented by the CIF file [CIF]
