  Pyridin type complexes of transition-metalhalides

  摘要：

  A large number of Co-picoline-chlorides were prepared from different reaction media by changing the Co: picoline molar ratio.A new solid-gas phase method is described to prepare ternary mixed Co-picoline complexes containing different picolines.According to the thermal and spectral investigations the ligand chemisorption from the vapour phase depends on the stability of the solid complex and the complex formation ability of the ligand in the gas phase.

  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)

  CoX2 (X=Cl, Br) 在 4-甲基吡啶 (4-Me-py) 和 2-甲基吡啶 (2-Me-​​py) 溶液中的可见吸收光谱已在 1 bar -3 的压力范围内测量kbar 在室温下，在 ≈6–≈75 °C 的温度范围内，1 bar。在4-Me-py解系统中，构型平衡，[CoX2(4-Me-py)2](四面体)+2(4-Me-py)\ightleftarrows[CoX2(4-Me-py)4] （八面体），被发现存在于实验压力范围内。增加压力使平衡向八面体物质侧移动，氯配合物的体积变化为 -26 cm3mol-1，溴配合物的体积变化为 -25 cm3mol-1，压力为 1 bar。上述平衡在氯配合物的整个实验温度范围内保持得相当好，但在溴配合物的有限温度范围内。

  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.
