The compound described by CsMg6Ni crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent Mg(4), 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 single-bond geometry to two equivalent Mg(3), two equivalent Mg(4), and one Ni(1) atom. In the second Mg site, Mg(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Cs(1), one Mg(4), and two equivalent Ni(1) atoms. In the third Mg site, Mg(3) is bonded in a distorted hexagonal planar geometry to two equivalent Mg(4) and four equivalent Mg(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to two equivalent Cs(1), two equivalent Mg(1), and four equivalent Mg(2) atoms. is represented by the CIF file [CIF]
