Ag3Bi4 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 bent 150 degrees geometry to one Ag(3) and one Bi(3) atom. The Ag(1)-Ag(3) bond length is 0.74 Å. The Ag(1)-Bi(3) bond length is 2.42 Å. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to one Bi(2), one Bi(3), and one Bi(4) atom. The Ag(2)-Bi(2) bond length is 3.06 Å. The Ag(2)-Bi(3) bond length is 1.89 Å. The Ag(2)-Bi(4) bond length is 2.23 Å. In the third Ag site, Ag(3) is bonded in a distorted bent 120 degrees geometry to one Ag(1) and one Bi(4) atom. The Ag(3)-Bi(4) bond length is 1.85 Å. There are four inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted single-bond geometry to one Bi(2), one Bi(3), and one Bi(4) atom. The Bi(1)-Bi(2) bond length is 0.40 Å. The Bi(1)-Bi(3) bond length is 2.64 Å. The Bi(1)-Bi(4) bond length is 2.58 Å. In the second Bi site, Bi(2) is bonded in a distorted single-bond geometry to one Ag(2) and one Bi(1) atom. In the third Bi site, Bi(3) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Bi(1), and one Bi(4) atom. The Bi(3)-Bi(4) bond length is 2.43 Å. In the fourth Bi site, Bi(4) is bonded in a 4-coordinate geometry to one Ag(2), one Ag(3), one Bi(1), and one Bi(3) atom.
