Özet

Nine CuII complexes (I-IX) containing the azide ion and bis-2,6-(pyrazol-1-yl)pyridine (pp), bis-2,6-(pyrazol-1-yl)pyridine (dmpp), and 2-(pyrazol-1-yl)-6-(3,5-dimethylpyrazol-1-yl)pyridine (mpp), which are derivatives of pyrazolylpyridine, were prepared in nonaqueous medium. These complexes were characterized by elemental analyses and IR spectroscopy. Crystals of one of these complexes [CumppClN3 (VII)] were prepared in suitable size, and a molecular structure of this complex was obtained with X-ray diffraction method. Complexes were examined by thermogravimetry and differential scanning calorimetry methods. Thermal decomposition was observed in complexes including two azide groups similar to that seen in explosives. In the complexes containing one azide group, formation of the CuI complexes was observed after thermal decomposition of the azide group. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
