MgZn2(WO4)2 crystallizes in the monoclinic C2 space group. Mg(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form MgO4 tetrahedra that share corners with two equivalent W(1)O6 octahedra, corners with two equivalent W(2)O6 octahedra, and  an edgeedge with one Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-56°. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with two equivalent Zn(1)O6 octahedra, corners with two equivalent Mg(1)O4 tetrahedra, edges with two equivalent W(2)O6 octahedra, and edges with two equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 31°.
