The structure described by Er3Co6Sn5 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 Co(2) and eight equivalent Sn(1) atoms to form distorted ErCo4Sn8 cuboctahedra that share edges with two equivalent Sn(2)Er4Co8 cuboctahedra and faces with two equivalent Er(1)Co4Sn8 cuboctahedra. In the second Er site, Er(2) is bonded in a 14-coordinate geometry to two equivalent Co(1), four equivalent Co(2), two equivalent Sn(2), and six equivalent Sn(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 10-coordinate geometry to two equivalent Er(2), four equivalent Co(2), two equivalent Sn(1), and two equivalent Sn(2) atoms. In the second Co site, Co(2) is bonded in a 10-coordinate geometry to one Er(1), two equivalent Er(2), one Co(2), two equivalent Co(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Er(1), three equivalent Er(2), one Co(1), three equivalent Co(2), and one Sn(1) atom. In the second Sn site, Sn(2) is bonded to four equivalent Er(2), four equivalent Co(1), and four equivalent Co(2) atoms to form SnEr4Co8 cuboctahedra that share edges with two equivalent Er(1)Co4Sn8 cuboctahedra and faces with two equivalent Sn(2)Er4Co8 cuboctahedra. is represented by the CIF card [CIF]
