CoOOH is Pb(Zr_(1-x)Ti_x)O3-like structured and crystallizes in the triclinic P-1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form edge-sharing CoO6 octahedra. In the second Co site, Co(2) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing CoO6 octahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(1) and one O(4) atom. In the second H site, H(2) is bonded in a linear geometry to one O(2) and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one H(1) atom. 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 H(2) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), and one H(2) atom. In the fourth O site, O(4) is bonded to one Co(2), two equivalent Co(1), and one H(1) atom to form distorted edge-sharing OCo3H tetrahedra.
