The compound described by Ho11Ge10 is delta Molybdenum Boride-like structured and crystallizes in the tetragonal I4/mmm space group. There are four inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 7-coordinate geometry to one Ge(2), two equivalent Ge(1), two equivalent Ge(3), and two equivalent Ge(5) atoms. In the second Ho site, Ho(2) is bonded in a 9-coordinate geometry to one Ge(4), four equivalent Ge(1), and four equivalent Ge(3) atoms. In the third Ho site, Ho(3) is bonded in a 7-coordinate geometry to one Ge(3), two equivalent Ge(1), two equivalent Ge(4), and two equivalent Ge(5) atoms. In the fourth Ho site, Ho(4) is bonded to one Ge(2), one Ge(4), one Ge(5), and four equivalent Ge(1) atoms to form a mixture of distorted corner, face, and edge-sharing HoGe7 pentagonal bipyramids. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Ho(2), one Ho(3), two equivalent Ho(1), four equivalent Ho(4), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent Ho(4) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to one Ho(3), two equivalent Ho(2), four equivalent Ho(1), and two equivalent Ge(3) atoms. In the fourth Ge site, Ge(4) is bonded in a 9-coordinate geometry to one Ho(2), four equivalent Ho(3), and four equivalent Ho(4) atoms. In the fifth Ge site, Ge(5) is bonded in a 8-coordinate geometry to two equivalent Ho(3), two equivalent Ho(4), and four equivalent Ho(1) atoms. is represented by the CIF file [CIF]
