The crystal structure described by Ho6Co2Sn 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 Co(1), one Co(2), one Sn(1), and one Sn(2) atom. In the second Ho site, Ho(2) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(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 Co(2), two equivalent Co(1), and one Sn(1) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), four equivalent Ho(3), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(3), four equivalent Ho(2), and one Co(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 Crystallographic Information File (CIF) [CIF]
