The crystal structure described by Mg2WCoO6 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 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, corners with six equivalent Mg(2)O6 octahedra, edges with three equivalent Co(1)O6 octahedra, and  a faceface with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-57°. 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 Co(1)O6 octahedra, corners with six equivalent Mg(1)O6 octahedra, edges with three equivalent W(1)O6 octahedra, and  a faceface with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-64°. 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(1)O6 octahedra, corners with six equivalent Co(1)O6 octahedra, edges with three equivalent Mg(2)O6 octahedra, and  a faceface with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-57°. Co(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 distorted CoO6 octahedra that share corners with three equivalent Mg(2)O6 octahedra, corners with six equivalent W(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, and  a faceface with one Mg(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-64°. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Mg(2), one W(1), and one Co(1) atom to form a mixture of distorted corner and edge-sharing OMg2CoW trigonal pyramids. In the second O site, O(2) is bonded to one Mg(1), one Mg(2), one W(1), and one Co(1) atom to form a mixture of distorted corner and edge-sharing OMg2CoW trigonal pyramids. In the third O site, O(3) is bonded to one Mg(1), one Mg(2), one W(1), and one Co(1) atom to form a mixture of distorted corner and edge-sharing OMg2CoW trigonal pyramids. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Co(1) atom. In the fifth O site, O(5) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Co(1) atom. In the sixth O site, O(6) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Mg(2), one W(1), and one Co(1) atom. is represented by the CIF card [CIF]
