The material structure described by ErAgSn crystallizes in the hexagonal P-62m space group. Er(1) is bonded in a 11-coordinate geometry to six equivalent Ag(1), one Sn(1), and four equivalent Sn(2) atoms. Ag(1) is bonded to six equivalent Er(1), two equivalent Ag(1), two equivalent Sn(1), and two equivalent Sn(2) atoms to form a mixture of distorted face, corner, and edge-sharing AgEr6Ag2Sn4 cuboctahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent Er(1) and six equivalent Ag(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to six equivalent Er(1) and three equivalent Ag(1) atoms. is represented by the CIF file [CIF]
