The material described by Mg2WCrO6 is Corundum-derived structured and crystallizes in the triclinic P1 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second Mg site, Mg(2) 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 MgO6 octahedra that share corners with three equivalent W(1)O6 octahedra, edges with three equivalent Cr(1)O6 octahedra, and  a faceface with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 60-61°. 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 WO6 octahedra that share corners with three equivalent Mg(2)O6 octahedra, corners with six equivalent Cr(1)O6 octahedra, and  a faceface with one Mg(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-61°. Cr(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 CrO6 octahedra that share corners with six equivalent W(1)O6 octahedra and edges with three equivalent Mg(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-42°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Cr(1) atom. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Cr(1) atom. In the fifth O site, O(5) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Cr(1) atom. In the sixth O site, O(6) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Cr(1) atom. is represented by the CIF file [CIF]
