YNiAg2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YNiAg2 clusters. Y(1) is bonded in a single-bond geometry to one Ni(1) and one Ag(2) atom. The Y(1)-Ni(1) bond length is 0.32 Å. The Y(1)-Ag(2) bond length is 2.91 Å. Ni(1) is bonded in a single-bond geometry to one Y(1) and one Ag(1) atom. The Ni(1)-Ag(1) bond length is 2.59 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Ni(1) atom. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Y(1) atom.
