The structure described by Sm3NiGe2 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 6-coordinate geometry to one Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Sm site, Sm(2) is bonded in a 7-coordinate geometry to two equivalent Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the third Sm site, Sm(3) is bonded in a 8-coordinate geometry to three equivalent Ni(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to one Sm(1), two equivalent Sm(2), three equivalent Sm(3), one Ge(2), and two equivalent Ge(1) 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(1), two equivalent Sm(2), three equivalent Sm(3), and two equivalent Ni(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Sm(3), three equivalent Sm(1), three equivalent Sm(2), and one Ni(1) atom. is represented by the CIF file [CIF]
