The material described by Er6Co2Ga crystallizes in the orthorhombic Immm space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one Ga(1), and one Ga(2) atom. In the second Er site, Er(2) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one Ga(2) atom. In the third Er site, Er(3) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), one Ga(1), and one Ga(2) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(3), four equivalent Er(2), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(2), four equivalent Er(3), and one Co(2) atom. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a body-centered cubic geometry to four equivalent Er(1) and four equivalent Er(3) atoms. In the second Ga site, Ga(2) is bonded in a cuboctahedral geometry to four equivalent Er(1), four equivalent Er(2), and four equivalent Er(3) atoms. is represented by the CIF card [CIF]
