The material described by Ho is alpha Samarium structured and crystallizes in the trigonal R-3m space group. There are four 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 edge, corner, and face-sharing HoHo12 cuboctahedra. In the second Ho site, Ho(2) is bonded to three equivalent Ho(1) and nine Ho(2,2) atoms to form a mixture of edge, corner, and face-sharing HoHo12 cuboctahedra. In the third Ho site, Ho(2) is bonded to three equivalent Ho(1) and nine Ho(2,2) atoms to form a mixture of edge, corner, and face-sharing HoHo12 cuboctahedra. In the fourth Ho site, Ho(2) is bonded to three equivalent Ho(1) and nine Ho(2,2) atoms to form a mixture of edge, corner, and face-sharing HoHo12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
