The structure described by Ho2RuGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. In the second Ho site, Ho(2) is bonded in a 8-coordinate geometry to two equivalent Ru(1), one Ge(1), and five equivalent Ge(2) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to one Ho(2), five equivalent Ho(1), three equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), five equivalent Ho(2), one Ru(1), and one Ge(2) atom. is represented by the CIF card [CIF]
