The material structure described by Ho5Tl3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 6-coordinate geometry to six equivalent Tl(1) atoms. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to five equivalent Tl(1) atoms. Tl(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1) and five equivalent Ho(2) atoms. is represented by the CIF card [CIF]
