The material described by Sm2CoGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sm sites. In the first Sm site, Sm(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 Sm site, Sm(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 Sm(1), four equivalent Sm(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 Sm(2), five equivalent Sm(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 Sm(1), five equivalent Sm(2), three equivalent Co(1), and one Ge(2) atom. is represented by the CIF card [CIF]
