Two Mannich base ligands, [1-(di- n -butylamine- N -methyl)mercapto-1 H -benz-imidazole] ( L 1 ) and [1-(diphenylamine- N -methyl)mercapto-1 H -benzimidazole] ( L 2 ) have been synthesized and further reacted with Co(II), Ni(II), Cu(II) and Zn(II) ionsto afford their respective complexes. The progress of the reaction was monitored by thin layer chromatography. The structural elucidation of Mannich
两个曼尼希碱配体,[1-(二-正丁胺-N-甲基)巯基-1 H-苯并咪唑](L 1)和[1-(二苯胺-N-甲基)巯基-1 H-苯并咪唑] (L 2)已合成,并进一步与Co(II),Ni(II),Cu(II)和Zn(II)离子反应,以提供它们各自的络合物。反应进程通过薄层色谱法监测。曼尼希碱配体及其金属配合物的结构阐明是通过傅立叶变换红外(FTIR),紫外可见,核磁共振光谱(1 H NMR和13 C NMR)和原子吸收光谱(AAS)/电感耦合等离子体发射进行的光谱法(ICPES)。FTIR和NMR研究支持L 1和L 2的单阴离子双齿配位模式,而在AAS / ICP的基础上提出了金属配合物的四面体几何构型,磁矩和电子光谱数据。还研究了合成的化合物的发光行为,该发光行为表现出宽的发射带,表明所涉及跃迁的电荷转移性质。关键词:金属络合物,曼尼希碱,2-巯基苯并咪唑,发光牛。化学 Soc。埃塞俄比亚。
