SrAg3 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a single-bond geometry to one Ag(2), one Ag(3), and two equivalent Ag(1) atoms. The Sr(1)-Ag(2) bond length is 2.56 Å. The Sr(1)-Ag(3) bond length is 0.04 Å. There is one shorter (1.91 Å) and one longer (3.40 Å) Sr(1)-Ag(1) bond length. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent Sr(1), one Ag(3), and three equivalent Ag(2) atoms. The Ag(1)-Ag(3) bond length is 1.89 Å. There are a spread of Ag(1)-Ag(2) bond distances ranging from 3.14-3.18 Å. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Sr(1) and three equivalent Ag(1) atoms. In the third Ag site, Ag(3) is bonded in a single-bond geometry to one Sr(1) and one Ag(1) atom.
