The crystal structure described by Ho is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to six equivalent Ho(1) and six equivalent Ho(2) atoms to form a mixture of corner, face, and edge-sharing HoHo12 cuboctahedra. In the second Ho site, Ho(2) is bonded to six equivalent Ho(1) and six equivalent Ho(2) atoms to form a mixture of corner, face, and edge-sharing HoHo12 cuboctahedra. is represented by the CIF card [CIF]
