Na La La Y
NaLa2Y crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaLa2Y clusters. Na(1) is bonded in a single-bond geometry to two equivalent La(1) and one Y(1) atom. Both Na(1)-La(1) bond lengths are 0.50 Å. The Na(1)-Y(1) bond length is 0.41 Å. La(1) is bonded in a 3-coordinate geometry to one Na(1), one La(1), and one Y(1) atom. The La(1)-La(1) bond length is 0.41 Å. The La(1)-Y(1) bond length is 0.50 Å. Y(1) is bonded in a single-bond geometry to one Na(1) and two equivalent La(1) atoms.
