CoF3 is alpha Rhenium trioxide structured and crystallizes in the trigonal P321 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to three equivalent F(1) and three equivalent F(2) atoms to form corner-sharing CoF6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second Co site, Co(2) is bonded to six equivalent F(1) atoms to form corner-sharing CoF6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent F sites. In the first F site, F(1) is bonded in a linear geometry to one Co(1) and one Co(2) atom. In the second F site, F(2) is bonded in a linear geometry to two equivalent Co(1) atoms.
