Manganese trifluoride Production

The Synthesis and reactions of Manganese trifluoride (CAS NO.7783-53-1):
MnF3 can be prepared by treating a solution of MnF2 in anhydrous hydrogen fluoride with fluorine:
MnF2 + 0.5 F2 → MnF3
In the crystalline state, MnF3 resembles vanadium(III) fluoride: both feature octahedal metal centers with the same average M-F bond distances. In the Mn compound, however, is distorted (and hence a monoclinic unit cell vs. a higher symmetry one) due to the Jahn-Teller effect, with pairs of Mn-F distances of 1.79, 1.91, 2.09 A.[3][4][5] Jahn-Teller distortions are characteristic of the presence of four d-electrons in the valence shell
