The material structure described by Co(CuO2)4 crystallizes in the triclinic P-1 space group. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share edges with two equivalent Cu(2)O6 octahedra. There are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second Cu site, Cu(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CuO6 octahedra that share edges with two equivalent Co(1)O6 octahedra. In the third Cu site, Cu(3) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. In the fourth Cu site, Cu(4) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one Co(1), one Cu(3), and one Cu(4) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), one Cu(1), one Cu(2), and one Cu(4) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), one Cu(1), one Cu(2), and one Cu(3) atom. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to one Cu(2), one Cu(3), and one Cu(4) atom. is represented by the CIF card [CIF]
