The visible absorption spectra of CoX2 (X=Cl, Br) in solutions of both 4-methylpyridine (4-Me-py) and 2-methylpyridine (2-Me-py) have been measured in the pressure range of 1 bar −3 kbar at room temperature, and in the temperature range of ≈6–≈75 °C at 1 bar. In the 4-Me-py solution system, the configuration equilibrium, [CoX2(4-Me-py)2] (tetrahedral) +2(4-Me-py)\ightleftarrows[CoX2(4-Me-py)4] (octahedral)

CoBr2(R-py)2 type (where R-py=2-methyl-(2Me-py), 3-methyl-(3Me-py), 4-methyl-(4Me-py), 4-acetyl-(4Ac-py), and 4-cyanopyridine (4CN-py), and pyridine(py)) with TBA·Br (tetrabutylammonium bromide) in 1,2-dibromoethane have been investigated spectrophotometrically. In the presence of an excess of R-py, the dibromocomplex gives rise to the following configurational equilibrium:CoBr2(R-py)2+2R-py\oversetkc\ightlef

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.
