LiSr2Ge3 crystallizes in the orthorhombic Fmmm space group. Li(1) is bonded in a trigonal planar geometry to two equivalent Sr(1), four equivalent Sr(2), one Ge(2), and two equivalent Ge(1) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent Li(1), two equivalent Ge(2), and eight equivalent Ge(1) atoms to form distorted SrLi2Ge10 cuboctahedra that share edges with four equivalent Sr(1)Li2Ge10 cuboctahedra, edges with eight equivalent Sr(2)Li4Ge8 cuboctahedra, faces with four equivalent Sr(1)Li2Ge10 cuboctahedra, and faces with four equivalent Sr(2)Li4Ge8 cuboctahedra. In the second Sr site, Sr(2) is bonded to four equivalent Li(1), four equivalent Ge(1), and four equivalent Ge(2) atoms to form distorted SrLi4Ge8 cuboctahedra that share edges with four equivalent Sr(2)Li4Ge8 cuboctahedra, edges with eight equivalent Sr(1)Li2Ge10 cuboctahedra, faces with four equivalent Sr(1)Li2Ge10 cuboctahedra, and faces with four equivalent Sr(2)Li4Ge8 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to one Li(1), two equivalent Sr(2), and four equivalent Sr(1) atoms. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to one Li(1), two equivalent Sr(1), and four equivalent Sr(2) atoms.
LiSr2Ge3 crystallizes in the orthorhombic Fmmm space group. Li(1) is bonded in a trigonal planar geometry to two equivalent Sr(1), four equivalent Sr(2), one Ge(2), and two equivalent Ge(1) atoms. Both Li(1)-Sr(1) bond lengths are 3.44 Å. All Li(1)-Sr(2) bond lengths are 3.40 Å. The Li(1)-Ge(2) bond length is 2.51 Å. Both Li(1)-Ge(1) bond lengths are 2.50 Å. There are two inequivalent Sr sites.
