Ba Y Y Ag
BaY2Ag crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaY2Ag clusters. Ba(1) is bonded in a distorted bent 150 degrees geometry to one Y(2) and one Ag(1) atom. The Ba(1)-Y(2) bond length is 1.82 Å. The Ba(1)-Ag(1) bond length is 1.16 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a single-bond geometry to one Ag(1) atom. The Y(1)-Ag(1) bond length is 0.88 Å. In the second Y site, Y(2) is bonded in a single-bond geometry to one Ba(1) atom. Ag(1) is bonded in a bent 120 degrees geometry to one Ba(1) and one Y(1) atom.
