Sr Ag Ag Br
SrAg2Br is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrAg2Br cluster. Sr(1) is bonded in a single-bond geometry to one Br(1) atom. The Sr(1)-Br(1) bond length is 1.71 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Br(1) atom. The Ag(1)-Br(1) bond length is 0.95 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Br(1) atom. The Ag(2)-Br(1) bond length is 1.71 Å. Br(1) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1), one Ag(1), and one Ag(2) atom.
