l metal complexes [iron (II) (1a–6a), cobalt (II) (1b–6b) and nickel (II) (1c–6c)] were synthesized and fully characterized by elemental and spectroscopic analyses. Single-crystal X-ray diffraction analyses of five coordinated complexes 5a, 3b, 5b, 1c and 2c reveal 5a and 5b as distorted trigonal-bipyramidal geometry, and 3b, 1c and 2c as distorted square pyramidal geometry. All complexes performed
摘要 一系列 2-(1-异丙基-2-苯并咪唑基)-6-(1-芳基亚氨基乙基)吡啶基金属配合物 [铁 (II) (1a-6a)、钴 (II) (1b-6b) 和镍 (II ) (1c-6c)] 被合成并通过元素和光谱分析充分表征。五种配位配合物 5a、3b、5b、1c 和 2c 的单晶 X 射线衍射分析显示 5a 和 5b 为扭曲的三角双锥几何形状,3b、1c 和 2c 为扭曲的方形金字塔几何形状。所有配合物都在各种有机铝的帮助下进行乙烯反应。铁配合物在 MAO 和 MMAO 存在下表现出良好的活性。经 Et2AlCl 活化后,钴类似物表现出中等的乙烯反应性,而镍类似物表现出相对较高的活性。
