NaAgGe2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a single-bond geometry to one Ag(1) and two equivalent Ge(2) atoms. The Na(1)-Ag(1) bond length is 0.47 Å. There is one shorter (2.63 Å) and one longer (2.79 Å) Na(1)-Ge(2) bond length. Ag(1) is bonded in a single-bond geometry to one Na(1) and two equivalent Ge(1) atoms. There is one shorter (2.63 Å) and one longer (2.79 Å) Ag(1)-Ge(1) bond length. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to two equivalent Ag(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Both Ge(1)-Ge(1) bond lengths are 2.90 Å. There is one shorter (2.45 Å) and one longer (2.94 Å) Ge(1)-Ge(2) bond length. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Both Ge(2)-Ge(2) bond lengths are 2.90 Å.
