Özet

The Co(II) complexes I and II were prepared in nonaqueous solvents containing cyanate with pyrazolylpyridine ligands, namely, bis-2,6-(pyrazol-1-yl) pyridine (Pp) and bis-2,6-(3,5-dimethyl-pyrazol-1-yl) pyridine (Dmpp), respectively. These complexes were characterized with elemental analysis, IR spectroscopy, and X-ray diffraction techniques. X-ray diffraction study revealed that complex I was mononuclear and complex II was dinuclear and ionic. The ionic complex II has an octahedral cationic coordination sphere and a tetrahedral anionic coordination sphere. Thermogravimetry results showed that the thermal decomposition is starting with the carbon content of the pyrazolyl rings.
