The compound described by HoNd3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. Ho(1) is bonded to four equivalent Nd(2) and eight equivalent Nd(1) atoms to form HoNd12 cuboctahedra that share corners with four equivalent Ho(1)Nd12 cuboctahedra, corners with eight equivalent Nd(2)Nd8Ho4 cuboctahedra, edges with eight equivalent Ho(1)Nd12 cuboctahedra, edges with sixteen equivalent Nd(1)Nd8Ho4 cuboctahedra, faces with four equivalent Ho(1)Nd12 cuboctahedra, faces with six equivalent Nd(2)Nd8Ho4 cuboctahedra, and faces with eight equivalent Nd(1)Nd8Ho4 cuboctahedra. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to four equivalent Ho(1), four equivalent Nd(1), and four equivalent Nd(2) atoms to form NdNd8Ho4 cuboctahedra that share corners with twelve equivalent Nd(1)Nd8Ho4 cuboctahedra, edges with eight equivalent Ho(1)Nd12 cuboctahedra, edges with eight equivalent Nd(1)Nd8Ho4 cuboctahedra, edges with eight equivalent Nd(2)Nd8Ho4 cuboctahedra, faces with four equivalent Ho(1)Nd12 cuboctahedra, faces with four equivalent Nd(2)Nd8Ho4 cuboctahedra, and faces with ten equivalent Nd(1)Nd8Ho4 cuboctahedra. In the second Nd site, Nd(2) is bonded to four equivalent Ho(1) and eight equivalent Nd(1) atoms to form NdNd8Ho4 cuboctahedra that share corners with four equivalent Nd(2)Nd8Ho4 cuboctahedra, corners with eight equivalent Ho(1)Nd12 cuboctahedra, edges with eight equivalent Nd(2)Nd8Ho4 cuboctahedra, edges with sixteen equivalent Nd(1)Nd8Ho4 cuboctahedra, faces with four equivalent Nd(2)Nd8Ho4 cuboctahedra, faces with six equivalent Ho(1)Nd12 cuboctahedra, and faces with eight equivalent Nd(1)Nd8Ho4 cuboctahedra. is represented by the CIF file [CIF]
