The material structure described by MgCd2(CoO3)2 crystallizes in the trigonal R-3 space group. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share edges with six equivalent Co(1)O6 octahedra. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share edges with three equivalent Mg(1)O6 octahedra and edges with three equivalent Co(1)O6 octahedra. Cd(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to one Mg(1), two equivalent Co(1), and two equivalent Cd(1) atoms to form a mixture of distorted corner and edge-sharing OMgCd2Co2 trigonal bipyramids. is represented by the CIF card [CIF]
