The material described by Ho12Co5Bi crystallizes in the orthorhombic Immm space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 5-coordinate geometry to one Co(1), one Co(3), two equivalent Co(2), and one Bi(1) atom. In the second Ho site, Ho(2) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one Bi(1) atom. In the third Ho site, Ho(3) is bonded in a 2-coordinate geometry to one Co(1), one Co(2), one Co(3), and one Bi(1) atom. There are three 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(3), four equivalent Ho(2), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Ho(2), two equivalent Ho(3), four equivalent Ho(1), and one Co(2) atom. In the third Co site, Co(3) is bonded in a distorted body-centered cubic geometry to four equivalent Ho(1) and four equivalent Ho(3) atoms. Bi(1) is bonded in a cuboctahedral geometry to four equivalent Ho(1), four equivalent Ho(2), and four equivalent Ho(3) atoms. is represented by the CIF file [CIF]
