Pyridine-type complexes of transition-metal halides

Manganese(II) chloride complexes with 3,4- and 3,5-lutidine have been prepared. The crystal symmetry and cell dimensions have been calculated on the basis of powder diffraction data. The compounds were characterised also by FT-IR spectrometry. The thermal decomposition of the complexes has been studied by thermogravimetry and DSC. By plotting densities vs. molar mass, the diagram obtained has correspondence to similar observations in other solid metal-lutidine complex systems.
