The structure described by HoFeNi is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imma space group. Ho(1) is bonded in a 16-coordinate geometry to four equivalent Ho(1), six equivalent Fe(1), and six equivalent Ni(1) atoms. Fe(1) is bonded to six equivalent Ho(1), two equivalent Fe(1), and four equivalent Ni(1) atoms to form FeHo6Fe2Ni4 cuboctahedra that share corners with eight equivalent Ni(1)Ho6Fe4Ni2 cuboctahedra, corners with ten equivalent Fe(1)Ho6Fe2Ni4 cuboctahedra, edges with six equivalent Fe(1)Ho6Fe2Ni4 cuboctahedra, faces with six equivalent Fe(1)Ho6Fe2Ni4 cuboctahedra, and faces with twelve equivalent Ni(1)Ho6Fe4Ni2 cuboctahedra. Ni(1) is bonded to six equivalent Ho(1), four equivalent Fe(1), and two equivalent Ni(1) atoms to form NiHo6Fe4Ni2 cuboctahedra that share corners with eight equivalent Fe(1)Ho6Fe2Ni4 cuboctahedra, corners with ten equivalent Ni(1)Ho6Fe4Ni2 cuboctahedra, edges with six equivalent Ni(1)Ho6Fe4Ni2 cuboctahedra, faces with six equivalent Ni(1)Ho6Fe4Ni2 cuboctahedra, and faces with twelve equivalent Fe(1)Ho6Fe2Ni4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
