The compound described by Sm6Co2Ga crystallizes in the orthorhombic Immm space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one Ga(1), and one Ga(2) atom. In the second Sm site, Sm(2) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), one Ga(1), and one Ga(2) atom. In the third Sm site, Sm(3) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), and one Ga(2) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), two equivalent Sm(3), four equivalent Sm(2), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 8-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), and four equivalent Sm(3) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a body-centered cubic geometry to four equivalent Sm(1) and four equivalent Sm(2) atoms. In the second Ga site, Ga(2) is bonded in a distorted cuboctahedral geometry to four equivalent Sm(1), four equivalent Sm(2), and four equivalent Sm(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
