The material structure described by Sm3Ru2Ge4 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 Ge(2) and six equivalent Ge(1) atoms. In the second Sm site, Sm(2) is bonded in a 11-coordinate geometry to four equivalent Ru(1), three equivalent Ge(1), and four equivalent Ge(2) atoms. Ru(1) is bonded in a 8-coordinate geometry to 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 three equivalent Sm(1), three equivalent Sm(2), one Ru(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Sm(1), four equivalent Sm(2), and three equivalent Ru(1) atoms. is represented by the CIF file [CIF]
