Na Y Y Cl
NaY2Cl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaY2Cl cluster. Na(1) is bonded in a single-bond geometry to one Cl(1) atom. The Na(1)-Cl(1) bond length is 2.56 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted L-shaped geometry to one Y(2) and one Cl(1) atom. The Y(1)-Y(2) bond length is 0.85 Å. The Y(1)-Cl(1) bond length is 2.20 Å. In the second Y site, Y(2) is bonded in a 2-coordinate geometry to one Y(1) and one Cl(1) atom. The Y(2)-Cl(1) bond length is 2.39 Å. Cl(1) is bonded in a 3-coordinate geometry to one Na(1), one Y(1), and one Y(2) atom.
