The material structure described by Cu5Ho7Sb crystallizes in the tetragonal P4mm space group. There are seven inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to four equivalent Ho(5) and four equivalent Cu(2) atoms. In the second Ho site, Ho(2) is bonded in a 4-coordinate geometry to four equivalent Ho(6), one Cu(3), and four equivalent Cu(1) atoms. In the third Ho site, Ho(3) is bonded in a single-bond geometry to four equivalent Ho(5) and one Cu(3) atom. In the fourth Ho site, Ho(4) is bonded in a 8-coordinate geometry to four equivalent Cu(2) and four equivalent Sb(1) atoms. In the fifth Ho site, Ho(5) is bonded in a 12-coordinate geometry to four equivalent Ho(1), four equivalent Ho(3), and four equivalent Cu(2) atoms. In the sixth Ho site, Ho(6) is bonded in a 9-coordinate geometry to four equivalent Ho(2), four equivalent Cu(1), and one Sb(1) atom. In the seventh Ho site, Ho(7) is bonded in a 8-coordinate geometry to four equivalent Cu(1) and four equivalent Cu(3) atoms. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to two equivalent Ho(2), two equivalent Ho(6), two equivalent Ho(7), and two equivalent Cu(3) atoms. In the second Cu site, Cu(2) is bonded in a 12-coordinate geometry to two equivalent Ho(1), two equivalent Ho(4), two equivalent Ho(5), four equivalent Cu(2), and two equivalent Sb(1) atoms. In the third Cu site, Cu(3) is bonded in a distorted single-bond geometry to one Ho(2), one Ho(3), four equivalent Ho(7), and four equivalent Cu(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to one Ho(6), four equivalent Ho(4), and four equivalent Cu(2) atoms. is represented by the CIF file [CIF]
