Ba Ba Ba Ba Ag Ag
Ba2Ag crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Ba2Ag clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one Ag(1) atom. The Ba(1)-Ag(1) bond length is 2.82 Å. In the second Ba site, Ba(2) is bonded in a single-bond geometry to one Ag(1) atom. The Ba(2)-Ag(1) bond length is 1.93 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ba(1) and one Ba(2) atom.
