The crystal structure described by MgZn2(WO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 4-coordinate geometry to one O(4), one O(5), one O(7), and one O(8) atom. 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(5), and one O(6) atom to form distorted WO6 octahedra that share corners with two equivalent Zn(1)O4 tetrahedra,  a cornercorner with one Zn(2)O5 trigonal bipyramid, edges with two equivalent W(2)O6 octahedra, and edges with two equivalent Zn(2)O5 trigonal bipyramids. In the second W site, W(2) 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 WO6 octahedra that share corners with three equivalent Zn(1)O4 tetrahedra,  a cornercorner with one Zn(2)O5 trigonal bipyramid, edges with two equivalent W(1)O6 octahedra, and  an edgeedge with one Zn(2)O5 trigonal bipyramid. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(3), one O(6), one O(7), and one O(8) atom to form ZnO4 tetrahedra that share corners with two equivalent W(1)O6 octahedra, corners with three equivalent W(2)O6 octahedra, and corners with two equivalent Zn(2)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 41-62°. In the second Zn site, Zn(2) is bonded to one O(1), one O(3), one O(4), one O(5), and one O(6) atom to form distorted ZnO5 trigonal bipyramids that share  a cornercorner with one W(1)O6 octahedra,  a cornercorner with one W(2)O6 octahedra, corners with two equivalent Zn(1)O4 tetrahedra,  an edgeedge with one W(2)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 26-67°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one W(1), one W(2), and one Zn(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one W(1) and one W(2) atom. In the third O site, O(3) is bonded in a distorted tetrahedral geometry to one W(1), one W(2), one Zn(1), and one Zn(2) 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 Zn(2) atom. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Mg(1), one W(1), and one Zn(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one W(1), one Zn(1), and one Zn(2) atom. In the seventh O site, O(7) is bonded in a trigonal planar geometry to one Mg(1), one W(2), and one Zn(1) atom. In the eighth O site, O(8) is bonded in a T-shaped geometry to one Mg(1), one W(2), and one Zn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
