The crystal structure described by Ho4Fe5Si3 crystallizes in the tetragonal P4mm space group. There are four inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 9-coordinate geometry to one Fe(3), four equivalent Fe(1), and four equivalent Si(2) atoms. In the second Ho site, Ho(2) is bonded in a 9-coordinate geometry to four equivalent Fe(2), one Si(1), and four equivalent Si(3) atoms. In the third Ho site, Ho(3) is bonded in a 9-coordinate geometry to four equivalent Fe(2), four equivalent Fe(3), and one Si(2) atom. In the fourth Ho site, Ho(4) is bonded in a 9-coordinate geometry to four equivalent Fe(1), one Si(3), and four equivalent Si(1) atoms. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 8-coordinate geometry to two equivalent Ho(1), two equivalent Ho(4), two equivalent Si(1), and two equivalent Si(2) atoms. In the second Fe site, Fe(2) is bonded in a 8-coordinate geometry to two equivalent Ho(2), two equivalent Ho(3), two equivalent Fe(3), and two equivalent Si(3) atoms.
