The compound described by Ba2CoF6 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 12-coordinate geometry to four equivalent F(1), four equivalent F(2), and four equivalent F(3) atoms. Co(1) is bonded to two equivalent F(1) and four equivalent F(3) atoms to form corner-sharing CoF6 octahedra. The corner-sharing octahedra are not tilted. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to four equivalent Ba(1) and one Co(1) atom. In the second F site, F(2) is bonded to four equivalent Ba(1) atoms to form a mixture of corner and edge-sharing FBa4 tetrahedra. In the third F site, F(3) is bonded in a linear geometry to four equivalent Ba(1) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
