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(2)O6 octahedra, corners with two equivalent Zn(1)O4 tetrahedra, corners with two equivalent Zn(2)O4 tetrahedra, and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 55°. 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 WO6 octahedra that share corners with two equivalent Zn(2)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, edges with two equivalent W(2)O6 octahedra, and  an edgeedge with one Mg(1)O4 tetrahedra. 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 WO6 octahedra that share corners with two equivalent Mg(1)O4 tetrahedra, corners with two equivalent Zn(1)O4 tetrahedra, corners with four equivalent Zn(2)O4 tetrahedra, and edges with two equivalent W(1)O6 octahedra.
