CrNi2Ag crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrNi2Ag cluster. Cr(1) is bonded in a distorted bent 150 degrees geometry to one Ni(1) and one Ag(1) atom. The Cr(1)-Ni(1) bond length is 1.75 Å. The Cr(1)-Ag(1) bond length is 1.25 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted water-like geometry to one Cr(1) and one Ni(2) atom. The Ni(1)-Ni(2) bond length is 0.92 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one Ni(1) atom. Ag(1) is bonded in a single-bond geometry to one Cr(1) atom.
