Toxic material.
Synthesis
Dissolve Mn2O3 in hydrofluoric acid and concentrate the solution for crystallization, or reduce potassium permanganate in hydrofluoric acid with low manganese salt to obtain hydrated manganese fluoride MnF3·3H2O. This compound is soluble in cold water and does not decompose, and is stable in hot water in the presence of hydrofluoric acid. Anhydrous manganese trifluoride is slowly decomposed into manganese difluoride, hydrated manganese dioxide and hydrogen fluoride in water.
Check Digit Verification of cas no
The CAS Registry Mumber 7783-53-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7783-53:
(6*7)+(5*7)+(4*8)+(3*3)+(2*5)+(1*3)=131
131 % 10 = 1
So 7783-53-1 is a valid CAS Registry Number.

Synthesis and structure of a tetragonal fluoroperovskitevariety deficient in cations - Cs4PdMn2F12
Fischer,Mller
, p. 1532 - 1536 (2008/10/08)
Single crystals of red Cs4PdMn2F12 were obtained by systematic investigations in the system CsF/MnF3/Pd/PdF3. The Compound crystallizes with a = b = 856.89(6) pm, c = 1918.35(18) pm, spcgr. I 41/amd - D4h19 (No. 141) and Z = 4. It is structurally related to K4MnMn2F12, but with square arrangement (isotypic?) of F- around Pd2+.

, p. 349 - 353 (2007/10/03)
The Knudsen effusion method with a mass spectrometric analysis of the gas phase was used to study vaporization of manganese di- and trifluorides. Saturated vapor pressures and the enthalpies of sublimation, Δ8H°(MnF2, 0 K) = 295 ± 11 kJ/mol and ΔsH°(MnF3, 0 K) = 267 ± 15 kJ/mol, were determined.
Kinetics of Fluorination of Manganese Compounds with Fluorine Gas
Rakov,Ostropikov,Khaustov
, p. 149 - 153 (2008/10/08)
The kinetics of fluorination of MnO2, MnF2, and KMnF3 powders by fluorine in nitrogen carrier gas at atmospheric pressure was studied by gravimetry. The kinetic equations of fluorination were deduced. MnO2 converts to MnF3 markedly more rapidly than MnF2. The volatile product (MnF4) forms above 780 K.
