Sr Sr Li Au
LiSr2Au crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiSr2Au clusters. Li(1) is bonded in an L-shaped geometry to one Sr(2) and one Au(1) atom. The Li(1)-Sr(2) bond length is 0.25 Å. The Li(1)-Au(1) bond length is 1.10 Å. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Au(1) atom. The Sr(1)-Au(1) bond length is 2.69 Å. In the second Sr site, Sr(2) is bonded in a distorted single-bond geometry to one Li(1) and one Au(1) atom. The Sr(2)-Au(1) bond length is 1.11 Å. Au(1) is bonded in a 3-coordinate geometry to one Li(1), one Sr(1), and one Sr(2) atom.
