The article deals with the conditions for anhydrous iron fluoride obtaining by thermal decomposition of iron trifluoride trihydrate. The basis of the $\beta$ -FeF $_{3} \cdot$ 3H $_{2}$ O crystal structure is outlined. Temperature limits of the $\beta$ -FeF $_{3} \cdot$ 3H $_{2}$ O phase decomposition as well as products of its dehydration are established. Nanocrystalline iron trifluoride of rhombic modification is obtained.

Key words: FeF $_{3}$ , crystal structure, thermal decomposition, Mössbauer spectroscopy, thermogravimetric analysis.
