The material described by Sr2MgWCdO6 crystallizes in the triclinic P-1 space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) 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. Cd(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Mg(1), one W(1), and one Cd(1) atom to form a mixture of edge and corner-sharing OSr2MgCdW trigonal bipyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1), one Mg(1), and one W(1) atom. 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 Cd(1) atom. is represented by the CIF file [CIF]
