The material structure described by Ho2CuGe6 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(4), two equivalent Ge(5), and four equivalent Ge(3) atoms. In the second Ho site, Ho(2) is bonded in a 14-coordinate geometry to four equivalent Cu(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(6), and four equivalent Ge(4) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Ho(2), one Ge(4), two equivalent Ge(1), and two equivalent Ge(6) atoms. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ho(2), two equivalent Cu(1), one Ge(2), and four equivalent Ge(6) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Ho(1), one Ge(1), and four equivalent Ge(5) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), and two equivalent Ge(4) atoms. In the fourth Ge site, Ge(4) is bonded in a 9-coordinate geometry to two equivalent Ho(1), four equivalent Ho(2), one Cu(1), and two equivalent Ge(3) atoms. In the fifth Ge site, Ge(5) is bonded in a 7-coordinate geometry to two equivalent Ho(1), one Ge(6), and four equivalent Ge(2) atoms. In the sixth Ge site, Ge(6) is bonded in a 9-coordinate geometry to two equivalent Ho(2), two equivalent Cu(1), one Ge(5), and four equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
