Pb2MgWO6 crystallizes in the cubic Fm-3m space group. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with eight equivalent Pb(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra and faces with eight equivalent Pb(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Pb(1) is bonded to twelve equivalent O(1) atoms to form PbO12 cuboctahedra that share corners with twelve equivalent Pb(1)O12 cuboctahedra, faces with six equivalent Pb(1)O12 cuboctahedra, faces with four equivalent Mg(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. O(1) is bonded in a linear geometry to one Mg(1), one W(1), and four equivalent Pb(1) atoms.
