The material described by ErAgSn crystallizes in the trigonal P-3m1 space group. Er(1) is bonded in a 9-coordinate geometry to six equivalent Ag(1) and six equivalent Sn(1) atoms. Ag(1) is bonded in a 10-coordinate geometry to six equivalent Er(1), three equivalent Ag(1), and one Sn(1) atom. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Er(1), one Ag(1), and three equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
