The material described by HoCo3Ni2 crystallizes in the hexagonal P6/mmm space group. Ho(1) is bonded in a distorted hexagonal planar geometry to twelve equivalent Co(1) and six equivalent Ni(1) atoms. Co(1) is bonded to four equivalent Ho(1), four equivalent Co(1), and four equivalent Ni(1) atoms to form CoHo4Co4Ni4 cuboctahedra that share corners with eight equivalent Ni(1)Ho3Co6 cuboctahedra, corners with sixteen equivalent Co(1)Ho4Co4Ni4 cuboctahedra, edges with eight equivalent Ni(1)Ho3Co6 cuboctahedra, edges with ten equivalent Co(1)Ho4Co4Ni4 cuboctahedra, faces with four equivalent Ni(1)Ho3Co6 cuboctahedra, and faces with ten equivalent Co(1)Ho4Co4Ni4 cuboctahedra. Ni(1) is bonded to three equivalent Ho(1) and six equivalent Co(1) atoms to form distorted NiHo3Co6 cuboctahedra that share corners with twelve equivalent Co(1)Ho4Co4Ni4 cuboctahedra, corners with fifteen equivalent Ni(1)Ho3Co6 cuboctahedra, edges with twelve equivalent Co(1)Ho4Co4Ni4 cuboctahedra, faces with five equivalent Ni(1)Ho3Co6 cuboctahedra, and faces with six equivalent Co(1)Ho4Co4Ni4 cuboctahedra. is represented by the CIF file [CIF]
