Investigation of Tetrahalogenoferrates(III) with Cations of Nitrogen-Containing Organic Bases. X-ray Crystal Structure of 2,6-Dimethylpyridinium Tetrabromoferrate(III)

The crystal and molecular structure of a new 2,6-dimethylpyridinium tetra bromo -ferrate(III), [2,6-LutH][FeBr4] was determined. The iron(III) cation adopts a slightly distorted tetrahedral coordination with one angle smaller than tetrahedral, three almost equal to the tetrahedral ones and two larger. The bond valences were computed. The total valence of the iron atom is equal to 3.24. In the structure N(1)–H(1)×××Br(3) hydrogen bond can be found.
