La2TaAg crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2TaAg clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 1-coordinate geometry to one Ta(1) atom. The La(1)-Ta(1) bond length is 3.41 Å. In the second La site, La(2) is bonded in a 1-coordinate geometry to one Ag(1) atom. The La(2)-Ag(1) bond length is 1.59 Å. Ta(1) is bonded in a 1-coordinate geometry to one La(1) and one Ag(1) atom. The Ta(1)-Ag(1) bond length is 2.75 Å. Ag(1) is bonded in a 1-coordinate geometry to one La(2) and one Ta(1) atom.
