Ba Ba Ag Ge
Ba2AgGe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ba2AgGe cluster. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 2-coordinate geometry to one Ag(1) and one Ge(1) atom. The Ba(1)-Ag(1) bond length is 3.02 Å. The Ba(1)-Ge(1) bond length is 2.32 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 1.81 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ba(1) and one Ba(2) atom. Ge(1) is bonded in a distorted single-bond geometry to one Ba(1) atom.
