Sr Li Li Nb
Li2SrNb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Li2SrNb cluster. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a single-bond geometry to one Nb(1) atom. The Li(1)-Nb(1) bond length is 0.48 Å. In the second Li site, Li(2) is bonded in a 1-coordinate geometry to one Nb(1) atom. The Li(2)-Nb(1) bond length is 2.79 Å. Sr(1) is bonded in a single-bond geometry to one Nb(1) atom. The Sr(1)-Nb(1) bond length is 2.10 Å. Nb(1) is bonded in a single-bond geometry to one Li(1), one Li(2), and one Sr(1) atom.
