Ag4As3Ag(As) crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of two Ag(As) clusters and one Ag4As3 cluster. In each Ag(As) cluster, Ag(2) is bonded in a single-bond geometry to one As(7) atom. The Ag(2)-As(7) bond length is 1.39 Å. As(7) is bonded in a distorted single-bond geometry to one Ag(2) atom. In the Ag4As3 cluster, there are eight inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to one Ag(6), one Ag(8), and one As(2) atom. The Ag(1)-Ag(6) bond length is 1.59 Å. The Ag(1)-Ag(8) bond length is 1.97 Å. The Ag(1)-As(2) bond length is 2.28 Å. In the second Ag site, Ag(3) is bonded in a single-bond geometry to one Ag(6) and one As(3) atom. The Ag(3)-Ag(6) bond length is 2.00 Å. The Ag(3)-As(3) bond length is 1.06 Å. In the third Ag site, Ag(4) is bonded in a 2-coordinate geometry to one Ag(5), one As(4), one As(5), one As(6), and one As(8) atom. The Ag(4)-Ag(5) bond length is 1.20 Å. The Ag(4)-As(4) bond length is 1.82 Å. The Ag(4)-As(5) bond length is 2.56 Å. The Ag(4)-As(6) bond length is 2.53 Å. The Ag(4)-As(8) bond length is 1.35 Å. In the fourth Ag site, Ag(5) is bonded in a 3-coordinate geometry to one Ag(4), one As(4), and one As(8) atom. The Ag(5)-As(4) bond length is 1.39 Å. The Ag(5)-As(8) bond length is 1.52 Å. In the fifth Ag site, Ag(6) is bonded in a 2-coordinate geometry to one Ag(1) and one Ag(3) atom. In the sixth Ag site, Ag(8) is bonded in a distorted trigonal non-coplanar geometry to one Ag(1), one Ag(9), and one As(5) atom. The Ag(8)-Ag(9) bond length is 1.39 Å. The Ag(8)-As(5) bond length is 1.91 Å. In the seventh Ag site, Ag(9) is bonded in a distorted single-bond geometry to one Ag(8) atom. In the eighth Ag site, Ag(10) is bonded in a single-bond geometry to one As(2) and one As(4) atom. The Ag(10)-As(2) bond length is 0.51 Å. The Ag(10)-As(4) bond length is 0.97 Å. There are six inequivalent As sites. In the first As site, As(2) is bonded in a single-bond geometry to one Ag(1), one Ag(10), and one As(4) atom. The As(2)-As(4) bond length is 1.04 Å. In the second As site, As(3) is bonded in a single-bond geometry to one Ag(3) atom. In the third As site, As(4) is bonded in a 4-coordinate geometry to one Ag(10), one Ag(4), one Ag(5), and one As(2) atom. In the fourth As site, As(5) is bonded in a 3-coordinate geometry to one Ag(4), one Ag(8), and one As(6) atom. The As(5)-As(6) bond length is 1.61 Å. In the fifth As site, As(6) is bonded in a 2-coordinate geometry to one Ag(4) and one As(5) atom. In the sixth As site, As(8) is bonded in a 1-coordinate geometry to one Ag(4) and one Ag(5) atom.
