The structure described by Mg(WO3)4 crystallizes in the cubic Im-3 space group. Mg(1) is bonded to twelve equivalent O(1) atoms to form MgO12 cuboctahedra that share faces with eight equivalent W(1)O6 octahedra. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with two equivalent Mg(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 19°. O(1) is bonded in a distorted T-shaped geometry to one Mg(1) and two equivalent W(1) atoms. is represented by the CIF card [CIF]
