The compound described by CsMg6Co crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded to two equivalent Cs(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms to form distorted CsCs2Mg10 cuboctahedra that share corners with six equivalent Cs(1)Cs2Mg10 cuboctahedra, edges with six equivalent Mg(3)Mg6 pentagonal pyramids, and faces with two equivalent Cs(1)Cs2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1), two equivalent Mg(3), and one Co(1) atom. In the second Mg site, Mg(2) is bonded in a distorted L-shaped geometry to two equivalent Cs(1), one Mg(3), and two equivalent Co(1) atoms. In the third Mg site, Mg(3) is bonded to two equivalent Mg(2) and four equivalent Mg(1) atoms to form distorted MgMg6 pentagonal pyramids that share edges with six equivalent Cs(1)Cs2Mg10 cuboctahedra and edges with two equivalent Mg(3)Mg6 pentagonal pyramids. In the fourth Mg site, Mg(4) is bonded in a distorted water-like geometry to two equivalent Cs(1) and two equivalent Co(1) atoms. Co(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(2) atoms. is represented by the CIF file [CIF]
