NaLa2Ta crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaLa2Ta cluster. Na(1) is bonded in a single-bond geometry to one La(1), one La(2), and one Ta(1) atom. The Na(1)-La(1) bond length is 1.22 Å. The Na(1)-La(2) bond length is 1.22 Å. The Na(1)-Ta(1) bond length is 0.13 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 3-coordinate geometry to one Na(1), one La(2), and one Ta(1) atom. The La(1)-La(2) bond length is 1.25 Å. The La(1)-Ta(1) bond length is 1.22 Å. In the second La site, La(2) is bonded in a 3-coordinate geometry to one Na(1), one La(1), and one Ta(1) atom. The La(2)-Ta(1) bond length is 1.22 Å. Ta(1) is bonded in a single-bond geometry to one Na(1), one La(1), and one La(2) atom.
