The material structure described by Ho6Ni2Sn crystallizes in the orthorhombic Immm space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 4-coordinate geometry to one Ni(1), one Ni(2), one Sn(1), and one Sn(2) atom. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to one Ni(1), two equivalent Ni(2), one Sn(1), and one Sn(2) atom. In the third Ho site, Ho(3) is bonded in a 4-coordinate geometry to one Ni(2), two equivalent Ni(1), and one Sn(1) atom. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), four equivalent Ho(3), and one Ni(1) atom. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(3), four equivalent Ho(2), and one Ni(2) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a cuboctahedral geometry to four equivalent Ho(1), four equivalent Ho(2), and four equivalent Ho(3) atoms. In the second Sn site, Sn(2) is bonded in a body-centered cubic geometry to four equivalent Ho(1) and four equivalent Ho(2) atoms. is represented by the CIF card [CIF]
