The structure described by Er3Ag3Ga8 crystallizes in the orthorhombic Immm space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded to four equivalent Ga(1) and eight equivalent Ga(2) atoms to form ErGa12 cuboctahedra that share edges with two equivalent Ag(1)Er4Ga4Ag4 cuboctahedra and faces with two equivalent Er(1)Ga12 cuboctahedra. In the second Er site, Er(2) is bonded in a 14-coordinate geometry to two equivalent Ag(1), two equivalent Ag(2), four equivalent Ga(2), and six equivalent Ga(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Er(2), four equivalent Ag(2), and four equivalent Ga(1) atoms to form distorted AgEr4Ga4Ag4 cuboctahedra that share edges with two equivalent Er(1)Ga12 cuboctahedra and faces with two equivalent Ag(1)Er4Ga4Ag4 cuboctahedra. In the second Ag site, Ag(2) is bonded in a 10-coordinate geometry to two equivalent Er(2), two equivalent Ag(1), two equivalent Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Er(1), three equivalent Er(2), one Ag(1), two equivalent Ag(2), and three equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(2), one Ag(2), one Ga(2), and three equivalent Ga(1) atoms. is represented by the CIF card [CIF]
