HoOOH crystallizes in the hexagonal P6_3/mmc space group. Ho(1) is bonded to six equivalent O(1) atoms to form edge-sharing HoO6 octahedra. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Ho(1) and one H(1) atom to form a mixture of distorted edge and corner-sharing OHo3H tetrahedra.
HoOOH crystallizes in the hexagonal P6_3/mmc space group. Ho(1) is bonded to six equivalent O(1) atoms to form edge-sharing HoO6 octahedra. All Ho(1)-O(1) bond lengths are 2.29 Å. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both H(1)-O(1) bond lengths are 1.23 Å. O(1) is bonded to three equivalent Ho(1) and one H(1) atom to form a mixture of distorted edge and corner-sharing OHo3H tetrahedra.
