Li Si Br Br
LiSiBr2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one LiSiBr2 cluster. Li(1) is bonded in a 2-coordinate geometry to one Si(1) and one Br(2) atom. The Li(1)-Si(1) bond length is 2.17 Å. The Li(1)-Br(2) bond length is 2.17 Å. Si(1) is bonded in a single-bond geometry to one Li(1), one Br(1), and one Br(2) atom. The Si(1)-Br(1) bond length is 1.31 Å. The Si(1)-Br(2) bond length is 0.39 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted single-bond geometry to one Si(1) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one Li(1) and one Si(1) atom.
