NiAg5 is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NiAg5 cluster. Ni(1) is bonded in a single-bond geometry to one Ag(2) and one Ag(5) atom. The Ni(1)-Ag(2) bond length is 2.20 Å. The Ni(1)-Ag(5) bond length is 0.41 Å. There are five inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Ag(2) and one Ag(3) atom. The Ag(1)-Ag(2) bond length is 2.41 Å. The Ag(1)-Ag(3) bond length is 1.78 Å. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one Ni(1), one Ag(1), and one Ag(3) atom. The Ag(2)-Ag(3) bond length is 2.20 Å. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one Ag(1), one Ag(2), and one Ag(4) atom. The Ag(3)-Ag(4) bond length is 1.64 Å. In the fourth Ag site, Ag(4) is bonded in a distorted single-bond geometry to one Ag(3) atom. In the fifth Ag site, Ag(5) is bonded in a single-bond geometry to one Ni(1) atom.
