Hf2Ag3 is Protactinium structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hf2Ag3 cluster. There are four inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a single-bond geometry to one Ag(3) atom. The Hf(1)-Ag(3) bond length is 1.42 Å. In the second Hf site, Hf(2) is bonded in a single-bond geometry to one Ag(4) and one Ag(6) atom. The Hf(2)-Ag(4) bond length is 0.94 Å. The Hf(2)-Ag(6) bond length is 3.19 Å. In the third Hf site, Hf(3) is bonded in a distorted L-shaped geometry to one Ag(1) and one Ag(2) atom. The Hf(3)-Ag(1) bond length is 1.01 Å. The Hf(3)-Ag(2) bond length is 1.28 Å. In the fourth Hf site, Hf(4) is bonded in a single-bond geometry to one Ag(2) atom. The Hf(4)-Ag(2) bond length is 1.39 Å. There are six inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Hf(3) and one Ag(6) atom. The Ag(1)-Ag(6) bond length is 1.18 Å. In the second Ag site, Ag(2) is bonded in a bent 120 degrees geometry to one Hf(3) and one Hf(4) atom. In the third Ag site, Ag(3) is bonded in a distorted bent 150 degrees geometry to one Hf(1) and one Ag(5) atom. The Ag(3)-Ag(5) bond length is 0.30 Å. In the fourth Ag site, Ag(4) is bonded in a distorted single-bond geometry to one Hf(2) and one Ag(5) atom. The Ag(4)-Ag(5) bond length is 1.13 Å. In the fifth Ag site, Ag(5) is bonded in a 2-coordinate geometry to one Ag(3) and one Ag(4) atom. In the sixth Ag site, Ag(6) is bonded in a distorted bent 150 degrees geometry to one Hf(2) and one Ag(1) atom.
