CoOOH crystallizes in the hexagonal P6_3/mmc space group. Co(1) is bonded to six equivalent O(1) atoms to form edge-sharing CoO6 octahedra. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to three equivalent Co(1) and one H(1) atom.
CoOOH crystallizes in the hexagonal P6_3/mmc space group. Co(1) is bonded to six equivalent O(1) atoms to form edge-sharing CoO6 octahedra. All Co(1)-O(1) bond lengths are 2.02 Å. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both H(1)-O(1) bond lengths are 1.21 Å. O(1) is bonded in a 4-coordinate geometry to three equivalent Co(1) and one H(1) atom.
