CoF3 crystallizes in the triclinic P-1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing CoF6 octahedra. The corner-sharing octahedral tilt angles range from 39-41°. In the second Co site, Co(2) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing CoF6 octahedra. The corner-sharing octahedral tilt angles range from 39-41°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Co(1) and one Co(2) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Co(1) and one Co(2) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Co(1) and one Co(2) atom.
