Li2SrW crystallizes in the triclinic P1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted single-bond geometry to one Sr(1) and four equivalent W(1) atoms. The Li(1)-Sr(1) bond length is 0.47 Å. There are a spread of Li(1)-W(1) bond distances ranging from 2.49-3.42 Å. In the second Li site, Li(2) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms. There is one shorter (2.85 Å) and one longer (3.40 Å) Li(2)-W(1) bond length. Sr(1) is bonded in a single-bond geometry to one Li(1) atom. W(1) is bonded in a 8-coordinate geometry to two equivalent Li(2), four equivalent Li(1), and two equivalent W(1) atoms. Both W(1)-W(1) bond lengths are 2.78 Å.
