CoOOH crystallizes in the triclinic P-1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to six equivalent O(1) atoms to form edge-sharing CoO6 octahedra. In the second Co site, Co(2) is bonded to six equivalent O(2) atoms to form edge-sharing CoO6 octahedra. H(1) is bonded in a distorted single-bond geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Co(1) and one H(1) atom to form a mixture of distorted edge and corner-sharing OCo3H tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Co(2) and one H(1) atom.
CoOOH crystallizes in the triclinic P-1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to six equivalent O(1) atoms to form edge-sharing CoO6 octahedra. There are four shorter (1.94 Å) and two longer (2.00 Å) Co(1)-O(1) bond lengths. In the second Co site, Co(2) is bonded to six equivalent O(2) atoms to form edge-sharing CoO6 octahedra. There are two shorter (2.03 Å) and four longer (2.04 Å) Co(2)-O(2) bond lengths. H(1) is bonded in a distorted single-bond geometry to one O(1) and one O(2) atom. The H(1)-O(1) bond length is 1.66 Å. The H(1)-O(2) bond length is 1.00 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Co(1) and one H(1) atom to form a mixture of distorted edge and corner-sharing OCo3H tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Co(2) and one H(1) atom.
