Na Ag Ag Ge
NaAg2Ge is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaAg2Ge cluster. Na(1) is bonded in an L-shaped geometry to one Ag(1) and one Ge(1) atom. The Na(1)-Ag(1) bond length is 0.52 Å. The Na(1)-Ge(1) bond length is 0.52 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Na(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 1.16 Å. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to one Ag(1) and one Ge(1) atom. The Ag(2)-Ge(1) bond length is 1.16 Å. Ge(1) is bonded in a single-bond geometry to one Na(1) and one Ag(2) atom.
