The material described by SrMg6Ni crystallizes in the orthorhombic Amm2 space group. Sr(1) is bonded in a 12-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(2), and two equivalent Ni(1) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1), two equivalent Mg(2), two equivalent Mg(4), and one Ni(1) atom. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Sr(1), one Mg(3), one Mg(4), two equivalent Mg(1), two equivalent Mg(2), and two equivalent Ni(1) atoms. In the third Mg site, Mg(3) is bonded in a 4-coordinate geometry to two equivalent Mg(2) 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), two equivalent Mg(3), and four equivalent Mg(1) atoms. Ni(1) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent Mg(1), and four equivalent Mg(2) atoms. is represented by the CIF card [CIF]
