Materials Data on SrLiGe2 by Materials Project

LiSrGe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li is bonded in a 5-coordinate geometry to five Ge atoms. There are one shorter (2.65 Å) and four longer (2.78 Å) Li–Ge bond lengths. Sr is bonded in a 5-coordinate geometry to nine Ge atoms. There are a spread of Sr–Ge bond distances ranging from 3.26–3.56 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent Li, four equivalent Sr, and two equivalent Ge atoms. There are one shorter (2.50 Å) and one longer (2.54 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Li, five equivalent Sr, and two equivalent Ge atoms.

Materials Data on Sr2LiGe3 by Materials Project

LiSr2Ge3 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. Li is bonded in a trigonal planar geometry to six Sr and three Ge atoms. There are four shorter (3.43 Å) and two longer (3.46 Å) Li–Sr bond lengths. All Li–Ge bond lengths are 2.53 Å. There are two inequivalent Sr sites. In the first Sr site, Sr is bonded to two equivalent Li and ten Ge atoms to form a mixture of distorted edge and face-sharing SrLi2Ge10 cuboctahedra. There are a spread of Sr–Ge bond distances ranging from 3.37–3.46 Å. In the second Sr site, Sr is bonded to four equivalent Li and eight Ge atoms to form a mixture of distorted edge and face-sharing SrLi4Ge8 cuboctahedra. There are four shorter (3.42 Å) and four longer (3.43 Å) Sr–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a distorted single-bond geometry to one Li and six Sr atoms. In the second Ge site, Ge is bonded in a distorted single-bond geometry to one Li and six Sr atoms.
