SrIr2Ag crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent Ir(1), two equivalent Ir(2), and two equivalent Ag(1) atoms. There is one shorter (2.02 Å) and one longer (2.84 Å) Sr(1)-Ir(1) bond length. There is one shorter (2.29 Å) and one longer (2.86 Å) Sr(1)-Ir(2) bond length. There is one shorter (2.29 Å) and one longer (2.86 Å) Sr(1)-Ag(1) bond length. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one Ir(2), and one Ag(1) atom. The Ir(1)-Ir(2) bond length is 1.34 Å. The Ir(1)-Ag(1) bond length is 1.34 Å. In the second Ir site, Ir(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one Ir(1) atom. Ag(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one Ir(1) atom.
