The material structure described by Ho5Ge3 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 Ge(1) atoms. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1) and five equivalent Ho(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
