The crystal structure described by Tm2CuGe6 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Tm sites. In the first Tm site, Tm(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(6) atoms. In the second Tm site, Tm(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(5) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Tm(2), one Ge(5), two equivalent Ge(1), and two equivalent Ge(3) atoms. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Tm(2), two equivalent Cu(1), one Ge(2), and four equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Tm(1), one Ge(1), and four equivalent Ge(4) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Tm(2), two equivalent Cu(1), one Ge(4), and four equivalent Ge(1) atoms. In the fourth Ge site, Ge(4) is bonded in a 7-coordinate geometry to two equivalent Tm(1), one Ge(3), and four equivalent Ge(2) atoms. In the fifth Ge site, Ge(5) is bonded in a 9-coordinate geometry to two equivalent Tm(1), four equivalent Tm(2), one Cu(1), and two equivalent Ge(6) atoms. In the sixth Ge site, Ge(6) is bonded in a 8-coordinate geometry to two equivalent Tm(2), four equivalent Tm(1), and two equivalent Ge(5) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
