Na Li Ag Ag
NaLiAg2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 1-coordinate geometry to one Li(1) and two equivalent Ag(1) atoms. The Na(1)-Li(1) bond length is 1.86 Å. There is one shorter (2.10 Å) and one longer (3.17 Å) Na(1)-Ag(1) bond length. Li(1) is bonded in a 4-coordinate geometry to one Na(1), one Ag(1), and two equivalent Ag(2) atoms. The Li(1)-Ag(1) bond length is 2.20 Å. There is one shorter (1.60 Å) and one longer (2.06 Å) Li(1)-Ag(2) bond length. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Li(1), and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 1.77 Å. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to two equivalent Li(1) and one Ag(1) atom.
