Materials Data on Sr3Li by Materials Project
LiSr3 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Li is bonded in a distorted square co-planar geometry to four equivalent Sr atoms. All Li–Sr bond lengths are 3.97 Å. There are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 8-coordinate geometry to eight Sr atoms. There are four shorter (3.97 Å) and four longer (4.13 Å) Sr–Sr bond lengths. In the second Sr site, Sr is bonded to four equivalent Li and eight equivalent Sr atoms to form a mixture of edge, face, and corner-sharing SrSr8Li4 cuboctahedra.
