Sr Li Li Mn
Li2SrMn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Li2SrMn clusters. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in an L-shaped geometry to one Sr(1) and one Mn(1) atom. The Li(1)-Sr(1) bond length is 0.85 Å. The Li(1)-Mn(1) bond length is 1.55 Å. In the second Li site, Li(2) is bonded in a single-bond geometry to one Mn(1) atom. The Li(2)-Mn(1) bond length is 2.56 Å. Sr(1) is bonded in a distorted single-bond geometry to one Li(1) and one Mn(1) atom. The Sr(1)-Mn(1) bond length is 1.82 Å. Mn(1) is bonded in a 3-coordinate geometry to one Li(1), one Li(2), and one Sr(1) atom.
