The structure described by HoFe2 is Hexagonal Laves structured and crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 12-coordinate geometry to three equivalent Fe(1), three equivalent Fe(3), and six equivalent Fe(2) atoms. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to six equivalent Ho(1), two equivalent Fe(3), and four equivalent Fe(2) atoms to form a mixture of face, corner, and edge-sharing FeHo6Fe6 cuboctahedra. In the second Fe site, Fe(2) is bonded to six equivalent Ho(1), two equivalent Fe(1), two equivalent Fe(2), and two equivalent Fe(3) atoms to form a mixture of face, corner, and edge-sharing FeHo6Fe6 cuboctahedra. In the third Fe site, Fe(3) is bonded to six equivalent Ho(1), two equivalent Fe(1), and four equivalent Fe(2) atoms to form a mixture of face, corner, and edge-sharing FeHo6Fe6 cuboctahedra. is represented by the CIF card [CIF]
