The structure described by Sr2MgWCoO6 crystallizes in the triclinic P-1 space group. Sr(1) is bonded in a 7-coordinate geometry to two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share faces with two equivalent W(1)O6 octahedra. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share faces with two equivalent Mg(1)O6 octahedra. Co(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Mg(1), and one W(1) atom. In the second O site, O(2) is bonded to two equivalent Sr(1), one Mg(1), one W(1), and one Co(1) atom to form a mixture of distorted edge and corner-sharing OSr2MgCoW trigonal bipyramids. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one Mg(1), one W(1), and one Co(1) atom. is represented by the CIF file [CIF]
