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.
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. There are three shorter (3.15 Å) and three longer (3.36 Å) Er(1)-Ag(1) bond lengths. There are three shorter (3.20 Å) and three longer (3.73 Å) Er(1)-Sn(1) bond lengths. Ag(1) is bonded in a 10-coordinate geometry to six equivalent Er(1), three equivalent Ag(1), and one Sn(1) atom. All Ag(1)-Ag(1) bond lengths are 2.82 Å. The Ag(1)-Sn(1) bond length is 3.04 Å. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Er(1), one Ag(1), and three equivalent Sn(1) atoms. All Sn(1)-Sn(1) bond lengths are 2.93 Å.
