The crystal structure described by Er(CoGa)6 crystallizes in the orthorhombic Immm space group. Er(1) is bonded in a 20-coordinate geometry to four equivalent Co(1), eight equivalent Co(2), two equivalent Ga(1), two equivalent Ga(3), and four equivalent Ga(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Er(1), four equivalent Co(2), two equivalent Ga(1), two equivalent Ga(2), and two equivalent Ga(3) atoms to form a mixture of distorted edge, face, and corner-sharing CoEr2Ga6Co4 cuboctahedra. In the second Co site, Co(2) is bonded to two equivalent Er(1), two equivalent Co(1), two equivalent Co(2), two equivalent Ga(1), two equivalent Ga(2), and two equivalent Ga(3) atoms to form a mixture of distorted edge, face, and corner-sharing CoEr2Ga6Co4 cuboctahedra. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Er(1), two equivalent Co(1), four equivalent Co(2), one Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to two equivalent Er(1), two equivalent Co(1), four equivalent Co(2), and two equivalent Ga(1) atoms. In the third Ga site, Ga(3) is bonded in a 8-coordinate geometry to one Er(1), two equivalent Co(1), four equivalent Co(2), and one Ga(3) atom. is represented by the CIF card [CIF]
