SrCaLa2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrCaLa2 cluster. Sr(1) is bonded in an L-shaped geometry to one La(1) and one La(2) atom. The Sr(1)-La(1) bond length is 1.98 Å. The Sr(1)-La(2) bond length is 1.98 Å. Ca(1) is bonded in a 1-coordinate geometry to one La(2) atom. The Ca(1)-La(2) bond length is 2.21 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. In the second La site, La(2) is bonded in a water-like geometry to one Sr(1) and one Ca(1) atom.
