The crystal structure described by SmCoGa2 crystallizes in the orthorhombic Cmmm space group. Sm(1) is bonded in a 14-coordinate geometry to four equivalent Co(1), two equivalent Ga(1), two equivalent Ga(2), and six equivalent Ga(3) atoms. Co(1) is bonded in a 10-coordinate geometry to four equivalent Sm(1), one Co(1), one Ga(3), two equivalent Ga(1), and two equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 12-coordinate geometry to four equivalent Sm(1), four equivalent Co(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to four equivalent Sm(1), four equivalent Co(1), and four equivalent Ga(1) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Co(1), and two equivalent Ga(3) atoms. is represented by the CIF card [CIF]
