Li2LaP is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Li2LaP clusters. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 2-coordinate geometry to one Li(2) and one La(1) atom. The Li(1)-Li(2) bond length is 0.67 Å. The Li(1)-La(1) bond length is 0.93 Å. In the second Li site, Li(2) is bonded in a distorted L-shaped geometry to one Li(1) and one La(1) atom. The Li(2)-La(1) bond length is 0.65 Å. La(1) is bonded in a 3-coordinate geometry to one Li(1), one Li(2), and one P(1) atom. The La(1)-P(1) bond length is 2.32 Å. P(1) is bonded in a single-bond geometry to one La(1) atom.
