The compound described by Sm3Co3Ga crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 9-coordinate geometry to two equivalent Co(2), four equivalent Co(1), and three equivalent Ga(1) atoms. In the second Sm site, Sm(2) is bonded in a 9-coordinate geometry to three equivalent Co(2), four equivalent Co(1), and two equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Sm(2), four equivalent Sm(1), one Co(2), and two equivalent Ga(1) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Sm(2), four equivalent Sm(1), and two equivalent Co(1) atoms. Ga(1) is bonded to two equivalent Sm(2), six equivalent Sm(1), and four equivalent Co(1) atoms to form a mixture of edge, face, and corner-sharing GaSm8Co4 cuboctahedra. is represented by the CIF card [CIF]
