Ho4In(NiGe2)2 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 three equivalent Ni(1), two equivalent In(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Ho site, Ho(2) is bonded in a 12-coordinate geometry to three equivalent Ni(1), two equivalent In(1), three equivalent Ge(2), and four equivalent Ge(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), one Ge(1), and three equivalent Ge(2) atoms. In(1) is bonded to four equivalent Ho(1), four equivalent Ho(2), two equivalent Ge(1), and two equivalent Ge(2) atoms to form face-sharing InHo8Ge4 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Ni(1), one In(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), three equivalent Ni(1), and one In(1) atom.
