CsMg6W crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent W(1) atoms to form a mixture of distorted corner and face-sharing CsMg10W2 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to two equivalent Cs(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent W(1) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Cs(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 1-coordinate geometry to two equivalent Cs(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(4), and one W(1) atom. In the fourth Mg site, Mg(4) is bonded in a 12-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent W(1) atoms. W(1) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Mg(3), two equivalent Mg(4), and four equivalent Mg(1) atoms.
