YAg4 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YAg4 clusters. Y(1) is bonded in a single-bond geometry to one Ag(4) atom. The Y(1)-Ag(4) bond length is 0.21 Å. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Ag(3) atom. The Ag(1)-Ag(3) bond length is 0.83 Å. In the second Ag site, Ag(2) is bonded in a linear geometry to one Ag(3) and one Ag(4) atom. The Ag(2)-Ag(3) bond length is 1.42 Å. The Ag(2)-Ag(4) bond length is 0.83 Å. In the third Ag site, Ag(3) is bonded in a linear geometry to one Ag(1) and one Ag(2) atom. In the fourth Ag site, Ag(4) is bonded in a single-bond geometry to one Y(1) and one Ag(2) atom.
