Ag3Ge4 crystallizes in the triclinic P1 space group. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Ag(3) and one Ge(2) atom. The Ag(1)-Ag(3) bond length is 1.37 Å. The Ag(1)-Ge(2) bond length is 2.73 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to one Ag(3), one Ge(1), one Ge(2), and one Ge(3) atom. The Ag(2)-Ag(3) bond length is 2.52 Å. The Ag(2)-Ge(1) bond length is 2.23 Å. The Ag(2)-Ge(2) bond length is 2.23 Å. The Ag(2)-Ge(3) bond length is 2.25 Å. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one Ag(1), one Ag(2), and one Ge(4) atom. The Ag(3)-Ge(4) bond length is 2.13 Å. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to one Ag(2), one Ge(2), one Ge(3), and one Ge(4) atom. The Ge(1)-Ge(2) bond length is 1.76 Å. The Ge(1)-Ge(3) bond length is 0.98 Å. The Ge(1)-Ge(4) bond length is 1.98 Å. In the second Ge site, Ge(2) is bonded in a 5-coordinate geometry to one Ag(1), one Ag(2), one Ge(1), one Ge(3), and one Ge(4) atom. The Ge(2)-Ge(3) bond length is 1.90 Å. The Ge(2)-Ge(4) bond length is 2.56 Å. In the third Ge site, Ge(3) is bonded in a single-bond geometry to one Ag(2), one Ge(1), and one Ge(2) atom. In the fourth Ge site, Ge(4) is bonded in a 2-coordinate geometry to one Ag(3), one Ge(1), and one Ge(2) atom.
