The material described by SrAg4Sb2 crystallizes in the trigonal R-3m space group. Sr(1) is bonded in a 14-coordinate geometry to two equivalent Ag(1), six equivalent Ag(2), and six equivalent Sb(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 11-coordinate geometry to one Sr(1), three equivalent Ag(1), three equivalent Ag(2), and four equivalent Sb(1) atoms. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent Sr(1), three equivalent Ag(1), and three equivalent Sb(1) atoms. Sb(1) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Ag(2), and four equivalent Ag(1) atoms. is represented by the CIF file [CIF]
