Ni Ag Ag Sb
NiAg2Sb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NiAg2Sb cluster. Ni(1) is bonded in a distorted single-bond geometry to one Ag(2) atom. The Ni(1)-Ag(2) bond length is 2.12 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Sb(1) atom. The Ag(1)-Sb(1) bond length is 0.88 Å. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Ni(1) and one Sb(1) atom. The Ag(2)-Sb(1) bond length is 1.06 Å. Sb(1) is bonded in a linear geometry to one Ag(1) and one Ag(2) atom.
