The material described by Sm3Ru2Ge2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Sm site, Sm(2) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. Ru(1) is bonded in a 9-coordinate geometry to two equivalent Sm(2), four equivalent Sm(1), one Ge(1), and two 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(2), four equivalent Sm(1), and two equivalent Ru(1) atoms. In the second Ge site, Ge(2) is bonded to two equivalent Sm(2), six equivalent Sm(1), and four equivalent Ru(1) atoms to form a mixture of distorted corner, edge, and face-sharing GeSm8Ru4 cuboctahedra. is represented by the CIF file [CIF]
