Na Sr La La
NaSrLa2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaSrLa2 clusters. Na(1) is bonded in a distorted single-bond geometry to one Sr(1) and one La(2) atom. The Na(1)-Sr(1) bond length is 0.73 Å. The Na(1)-La(2) bond length is 2.46 Å. Sr(1) is bonded in a distorted single-bond geometry to one Na(1) and one La(1) atom. The Sr(1)-La(1) bond length is 2.78 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second La site, La(2) is bonded in a single-bond geometry to one Na(1) atom.
