CsMgCoF6 crystallizes in the orthorhombic Imma space group. Cs(1) is bonded to one F(1), one F(2), and four equivalent F(3) atoms to form CsF6 octahedra that share corners with six equivalent Mg(1)F6 octahedra and corners with six equivalent Co(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 68-70°. Mg(1) is bonded to two equivalent F(2) and four equivalent F(3) atoms to form MgF6 octahedra that share corners with two equivalent Mg(1)F6 octahedra, corners with four equivalent Co(1)F6 octahedra, and corners with six equivalent Cs(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 41-70°. Co(1) is bonded to two equivalent F(1) and four equivalent F(3) atoms to form CoF6 octahedra that share corners with two equivalent Co(1)F6 octahedra, corners with four equivalent Mg(1)F6 octahedra, and corners with six equivalent Cs(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 41-69°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Cs(1) and two equivalent Co(1) atoms. In the second F site, F(2) is bonded in a 2-coordinate geometry to one Cs(1) and two equivalent Mg(1) atoms. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Cs(1), one Mg(1), and one Co(1) atom.
