CsMg6Mn crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Mn(1) atoms to form a mixture of corner and face-sharing CsMg10Mn2 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to two equivalent Cs(1), one Mg(2), and one Mn(1) atom. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), four equivalent Mg(3), and two equivalent Mn(1) atoms. In the third Mg site, Mg(3) is bonded in a 4-coordinate geometry to two equivalent Cs(1), two equivalent Mg(2), and two equivalent Mn(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 2-coordinate geometry to two equivalent Cs(1) and two equivalent Mg(2) atoms. Mn(1) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms.
