The material structure described by Sm3(CoGe2)2 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 10-coordinate geometry to three equivalent Co(1), three equivalent Ge(1), and five equivalent Ge(2) atoms. In the second Sm site, Sm(2) is bonded in a 6-coordinate geometry to two equivalent Ge(2) and six equivalent Ge(1) atoms. Co(1) is bonded in a 4-coordinate geometry to three equivalent Sm(1), 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 three equivalent Sm(1), three equivalent Sm(2), one Co(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Sm(2), five equivalent Sm(1), and three equivalent Co(1) atoms. is represented by the CIF file [CIF]
