The crystal structure described by SmCoGa4 crystallizes in the orthorhombic Cmcm space group. Sm(1) is bonded in a 15-coordinate geometry to two equivalent Co(1), three equivalent Ga(2), four equivalent Ga(3), and six equivalent Ga(1) atoms. Co(1) is bonded in a 7-coordinate geometry to two equivalent Sm(1), one Ga(2), and six equivalent Ga(1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 12-coordinate geometry to three equivalent Sm(1), three equivalent Co(1), one Ga(3), two equivalent Ga(2), and three equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 2-coordinate geometry to three equivalent Sm(1), one Co(1), four equivalent Ga(1), and four equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to four equivalent Sm(1), two equivalent Ga(1), and four equivalent Ga(2) atoms. is represented by the CIF card [CIF]
