(La)2SrBr crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one lanthanum molecule and one SrBr cluster. In the SrBr cluster, Sr(1) is bonded in a single-bond geometry to one Br(1) atom. The Sr(1)-Br(1) bond length is 0.75 Å. Br(1) is bonded in a single-bond geometry to one Sr(1) atom.
