The compound described by MgZn2(WO4)2 crystallizes in the monoclinic P2 space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted WO6 octahedra that share corners with two equivalent Zn(2)O4 trigonal pyramids and edges with two equivalent W(2)O6 octahedra. 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 Zn(2)O4 trigonal pyramids and edges with two equivalent W(1)O6 octahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(3) and two equivalent O(4) atoms. In the second Zn site, Zn(2) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form distorted ZnO4 trigonal pyramids that share corners with two equivalent W(1)O6 octahedra and corners with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-47°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one W(1), and one W(2) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1), one W(1), and one W(2) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one W(1), one Zn(1), and one Zn(2) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one W(2), one Zn(1), and one Zn(2) atom. is represented by the CIF file [CIF]
