The structure described by CrF3 crystallizes in the trigonal R-3c space group. Cr(1) is bonded to six equivalent F(1) atoms to form corner-sharing CrF6 octahedra. The corner-sharing octahedral tilt angles are 39°. F(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. is represented by the CIF card [CIF]
