Na Y Y Te
NaY2Te is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaY2Te clusters. Na(1) is bonded in a single-bond geometry to one Y(2) atom. The Na(1)-Y(2) bond length is 1.59 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a single-bond geometry to one Te(1) atom. The Y(1)-Te(1) bond length is 1.97 Å. In the second Y site, Y(2) is bonded in a linear geometry to one Na(1) and one Te(1) atom. The Y(2)-Te(1) bond length is 1.97 Å. Te(1) is bonded in a linear geometry to one Y(1) and one Y(2) atom.
