The material structure described by LiSrMg6 crystallizes in the orthorhombic Amm2 space group. Li(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. Sr(1) is bonded to two equivalent Li(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms to form SrLi2Mg10 cuboctahedra that share corners with six equivalent Sr(1)Li2Mg10 cuboctahedra, faces with two equivalent Sr(1)Li2Mg10 cuboctahedra, and faces with six equivalent Mg(2)Li2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to one Li(1), two equivalent Sr(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded to two equivalent Li(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms to form distorted MgLi2Mg10 cuboctahedra that share corners with six equivalent Mg(2)Li2Mg10 cuboctahedra, faces with two equivalent Mg(2)Li2Mg10 cuboctahedra, and faces with six equivalent Sr(1)Li2Mg10 cuboctahedra. In the third Mg site, Mg(3) is bonded in a 12-coordinate geometry to two equivalent Li(1), two equivalent Sr(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. is represented by the CIF file [CIF]
