vibrational spectra of the cobalt(II) complexes of methy-substituted pyridines have been systematically investigated in an effort to establish a general relationship between the electronicsteric requirments of the ligands and the stoichiometry, stereochemistry, and stability of the complexes. Some sixty complexes were examined, in which the anions were chloride, bromide, iodide and thiocyanate. The ligands
Abstract The thermal behaviour of transition-metal halide complexes formed with picoline was studied by derivatograph. The thermal decomposition of the complexes can take place either in molten or in solid phase in several steps. The mechanism of the step-wise reaction was also investigated.

Abstract In the preparation of cobalt(II)-picoline-bromide and iodide three different solvents were tested. Some new ternary mixed complexes were prepared containing different picolines using solid-gas phase preparation method. Themal and spectroscopic properties of the tittle compounds were investigated.
