The structure described by Er6Ni2Ga 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 Ni(1), one Ni(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 Ni(2), two equivalent Ni(1), and one Ga(2) atom. In the third Er site, Er(3) is bonded in a 4-coordinate geometry to one Ni(1), two equivalent Ni(2), one Ga(1), and one Ga(2) atom. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(3), four equivalent Er(2), and one Ni(1) atom. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(2), four equivalent Er(3), and one Ni(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]
