Sr2LaCl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2LaCl clusters. Sr(1) is bonded in a distorted L-shaped geometry to one La(1) and one Cl(1) atom. The Sr(1)-La(1) bond length is 1.64 Å. The Sr(1)-Cl(1) bond length is 1.64 Å. La(1) is bonded in an L-shaped geometry to two equivalent Sr(1) atoms. Cl(1) is bonded in an L-shaped geometry to two equivalent Sr(1) atoms.
