Ten hexadentate (N4O2, N4S2 and N6) Schiff-base ligands have been prepared by condensation of various aldehydes and two different linear tetraamines containing the piperazine moiety. The products have been characterised by melting point, elemental analysis and various spectroscopic methods such as: FT-IR, 1H, 13C NMR, and EI mass spectrometry. The complex [CoN, N'-bis[(pyridin-2-ylmethylene)ethyl
十个六齿(N4O2、N4S2 和 N6)席夫碱配体已通过各种醛和两种不同的包含哌嗪部分的线性四胺的缩合制备。产品已通过熔点、元素分析和各种光谱方法进行表征,例如:FT-IR、1H、13C NMR 和 EI 质谱。复合物 [CoN, N'-bis[(pyridin-2-ylmethylene)ethyl]piperazine}][ClO4]2 已制备。
