Onium hexacyanoferrates(II) with some halogenated anilines

Onium hexacyanoferrates(II) with 3- and 4-chloroaniline and 4-bromoaniline are studied by X-ray powder diffraction and thermal analyses and IR spectroscopy. The compounds are formed due to the protonation of the amino groups. The thermal stability of the complexes depends on the nature of outer-sphere amines. The kinetic parameters for the first step of thermal destruction of the complexes are calculated.
