Sr3Ag2 crystallizes in the trigonal R-3 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to five equivalent Ag(1) atoms. In the second Sr site, Sr(2) is bonded in an octahedral geometry to six equivalent Ag(1) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. Ag(1) is bonded in a 9-coordinate geometry to one Sr(2), two equivalent Sr(3), five equivalent Sr(1), and one Ag(1) atom.
Sr3Ag2 crystallizes in the trigonal R-3 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to five equivalent Ag(1) atoms. There are a spread of Sr(1)-Ag(1) bond distances ranging from 3.34-3.91 Å. In the second Sr site, Sr(2) is bonded in an octahedral geometry to six equivalent Ag(1) atoms. All Sr(2)-Ag(1) bond lengths are 3.42 Å. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. There are three shorter (3.26 Å) and three longer (3.39 Å) Sr(3)-Ag(1) bond lengths. Ag(1) is bonded in a 9-coordinate geometry to one Sr(2), two equivalent Sr(3), five equivalent Sr(1), and one Ag(1) atom. The Ag(1)-Ag(1) bond length is 2.96 Å.
