摘要:
4-Piperidinylpyridine and FeCl3 in CH3CN/conc. HCl yield the title compound, whose crystal structure shows almost tetrahedral [FeCl4](-) anions, and cations exhibiting the pyridinium tautomer. The temperature dependence of the Mossbauer spectra and AC susceptibility confirm a Neel temperature of approximately 2.5 K and an uncanted three-dimensional antiferromagnetic ground state.
