Correlations of conductometric and thermic properties with the structure of di(2-methylpyridinium)tetrachloromanganate(II)

Electric, thermic and spectral data of di(2-methylpyridinium)tetrachloromanganate(II) has been analyzed in terms of the structural properties of this salt. The dependence of the conductance on the absence or presence of the hydrogen bonding, as detected by the spectral studies for pyridinium salts containing polyatomic MnCl42- ions or chloride ions, respectively, has also been investigated. The experimental results indicate that the enhancement or decrease of the conductance is strongly affected by the specific position of the alkyl group in the pyridinium portion of the salts.
