The crystal structure described by HoFe6(Sn2Ge)2 crystallizes in the hexagonal P6/mmm space group. Ho(1) is bonded to twelve equivalent Fe(1), two equivalent Sn(2), and six equivalent Ge(1) atoms to form distorted HoFe12Sn2Ge6 hexagonal bipyramids that share faces with twenty-four equivalent Fe(1)Ho2Fe4Sn4Ge2 cuboctahedra and faces with six equivalent Ho(1)Fe12Sn2Ge6 hexagonal bipyramids. Fe(1) is bonded to two equivalent Ho(1), four equivalent Fe(1), two equivalent Sn(1), two equivalent Sn(2), and two equivalent Ge(1) atoms to form distorted FeHo2Fe4Sn4Ge2 cuboctahedra that share corners with fourteen equivalent Fe(1)Ho2Fe4Sn4Ge2 cuboctahedra, edges with seven equivalent Fe(1)Ho2Fe4Sn4Ge2 cuboctahedra, faces with nine equivalent Fe(1)Ho2Fe4Sn4Ge2 cuboctahedra, and faces with four equivalent Ho(1)Fe12Sn2Ge6 hexagonal bipyramids. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to six equivalent Fe(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to one Ho(1), six equivalent Fe(1), and one Sn(2) atom. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
