Cd(CoO2)2 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form edge-sharing CoO6 octahedra. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing CoO6 octahedra. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Co(2), two equivalent Co(1), one Cd(1), and one Cd(2) atom to form distorted OCd2Co3 trigonal bipyramids that share corners with five equivalent O(1)Cd2Co3 trigonal bipyramids, corners with two equivalent O(3)CdCo3 trigonal pyramids, edges with four equivalent O(1)Cd2Co3 trigonal bipyramids, and edges with two equivalent O(3)CdCo3 trigonal pyramids. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), two equivalent Co(2), and one Cd(2) atom. In the third O site, O(3) is bonded to one Co(1), two equivalent Co(2), and one Cd(1) atom to form OCdCo3 trigonal pyramids that share corners with four equivalent O(1)Cd2Co3 trigonal bipyramids, corners with three equivalent O(3)CdCo3 trigonal pyramids, and edges with four equivalent O(1)Cd2Co3 trigonal bipyramids.

In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing CoO6 octahedra. Both Co(2)-O(1) bond lengths are 1.93 Å. Both Co(2)-O(2) bond lengths are 1.89 Å. Both Co(2)-O(3) bond lengths are 1.90 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. Both Cd(1)-O(3) bond lengths are 2.24 Å. All Cd(1)-O(1) bond lengths are 2.41 Å. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms.
