The material structure described by Sm(CuGa2)4 crystallizes in the hexagonal P6/mmm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 20-coordinate geometry to twelve equivalent Cu(1), two equivalent Ga(3), and six equivalent Ga(4) atoms. In the second Sm site, Sm(2) is bonded in a 20-coordinate geometry to six equivalent Cu(1), two equivalent Ga(2), six equivalent Ga(1), and six equivalent Ga(5) atoms. Cu(1) is bonded to one Sm(1), one Sm(2), two equivalent Cu(1), one Ga(2), one Ga(3), two equivalent Ga(1), two equivalent Ga(4), and two equivalent Ga(5) atoms to form distorted CuSm2Ga8Cu2 cuboctahedra that share corners with five equivalent Ga(1)Sm2Ga6Cu4 cuboctahedra, corners with nine equivalent Cu(1)Sm2Ga8Cu2 cuboctahedra, edges with three equivalent Cu(1)Sm2Ga8Cu2 cuboctahedra, edges with three equivalent Ga(1)Sm2Ga6Cu4 cuboctahedra, faces with two equivalent Ga(1)Sm2Ga6Cu4 cuboctahedra, and faces with eight equivalent Cu(1)Sm2Ga8Cu2 cuboctahedra. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to two equivalent Sm(2), four equivalent Cu(1), two equivalent Ga(2), two equivalent Ga(4), and two equivalent Ga(5) atoms to form distorted GaSm2Ga6Cu4 cuboctahedra that share corners with four equivalent Ga(1)Sm2Ga6Cu4 cuboctahedra, corners with ten equivalent Cu(1)Sm2Ga8Cu2 cuboctahedra,  an edgeedge with one Ga(1)Sm2Ga6Cu4 cuboctahedra, edges with six equivalent Cu(1)Sm2Ga8Cu2 cuboctahedra, faces with four equivalent Cu(1)Sm2Ga8Cu2 cuboctahedra, and faces with five equivalent Ga(1)Sm2Ga6Cu4 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to one Sm(2), three equivalent Cu(1), one Ga(2), and three equivalent Ga(1) atoms. In the third Ga site, Ga(3) is bonded in a 14-coordinate geometry to one Sm(1), six equivalent Cu(1), one Ga(3), and six equivalent Ga(5) atoms. In the fourth Ga site, Ga(4) is bonded in a 8-coordinate geometry to one Sm(1), four equivalent Cu(1), one Ga(4), and two equivalent Ga(1) atoms. In the fifth Ga site, Ga(5) is bonded in a 12-coordinate geometry to two equivalent Sm(2), four equivalent Cu(1), two equivalent Ga(1), two equivalent Ga(3), and two equivalent Ga(5) atoms. is represented by the CIF card [CIF]
