The compound described by Tm2CoGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 8-coordinate geometry to two equivalent Co(1), one Ge(2), and five equivalent Ge(1) atoms. In the second Tm site, Tm(2) is bonded in a 11-coordinate geometry to four equivalent Co(1), two equivalent Ge(1), and five equivalent Ge(2) atoms. Co(1) is bonded in a 10-coordinate geometry to two equivalent Tm(1), four equivalent Tm(2), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Tm(2), five equivalent Tm(1), one Co(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Tm(1), five equivalent Tm(2), three equivalent Co(1), and one Ge(2) atom. is represented by the CIF card [CIF]
