The structure described by MgCd2(CoO3)2 crystallizes in the triclinic P1 space group. 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 Co(2)O6 octahedra, edges with three equivalent Co(1)O6 octahedra, and  a faceface with one Co(2)O6 octahedra. The corner-sharing octahedral tilt angles are 32°. There are two inequivalent Co sites.
