MgLu6WO12 is Corundum-derived structured and crystallizes in the trigonal R-3 space group. Mg(1) is bonded to six equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Lu(1)O6 pentagonal pyramids and edges with six equivalent Lu(1)O6 pentagonal pyramids. Lu(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted LuO6 pentagonal pyramids that share  a cornercorner with one Mg(1)O6 octahedra,  a cornercorner with one W(1)O6 octahedra, corners with four equivalent Lu(1)O6 pentagonal pyramids,  an edgeedge with one Mg(1)O6 octahedra,  an edgeedge with one W(1)O6 octahedra, and edges with four equivalent Lu(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 34-48°. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Lu(1)O6 pentagonal pyramids and edges with six equivalent Lu(1)O6 pentagonal pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Lu(1) and one W(1) atom to form a mixture of distorted corner and edge-sharing OLu3W trigonal pyramids. In the second O site, O(2) is bonded in a see-saw-like geometry to one Mg(1) and three equivalent Lu(1) atoms.

Mg(1) is bonded to six equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Lu(1)O6 pentagonal pyramids and edges with six equivalent Lu(1)O6 pentagonal pyramids. All Mg(1)-O(2) bond lengths are 2.10 Å. Lu(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted LuO6 pentagonal pyramids that share  a cornercorner with one Mg(1)O6 octahedra,  a cornercorner with one W(1)O6 octahedra, corners with four equivalent Lu(1)O6 pentagonal pyramids,  an edgeedge with one Mg(1)O6 octahedra,  an edgeedge with one W(1)O6 octahedra, and edges with four equivalent Lu(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 34-48°. There are a spread of Lu(1)-O(1) bond distances ranging from 2.19-2.36 Å. There are two shorter (2.19 Å) and one longer (2.20 Å) Lu(1)-O(2) bond length.
