The compound 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(3), and four equivalent Mg(2) atoms. Sr(1) is bonded to two equivalent Li(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms to form a mixture of face and corner-sharing SrLi2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to one 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 second Mg site, Mg(2) is bonded in a 11-coordinate geometry to two equivalent Li(1), two equivalent Sr(1), one Mg(4), two equivalent Mg(1), two equivalent Mg(2), and two equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 12-coordinate geometry to two equivalent Li(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
