大环异核配合物[CuML(H2O)n](ClO4)2的合成与表征

在金属离子存在下,用2,6-二甲酰基-对-正丁基苯酚与乙二胺和二乙烯三胺进行分步环缩合反应,合成了五种新型不对称的同核和异核大环配合物[CuML(H2O)n](ClO4)2(M=Cu,Mn,Zn,Cd和Ni;n=1,2),并用电喷雾质谱对它们在溶液中的存在形式进行了详细的研究.实验结果表明:[CuMnL(H2O)2](ClO4)2,[CuZnL(H2O)2](ClO4)2和[CuCdL(H2O)2](ClO4)2比[CuNiL(H2O)](ClO4)2和[CuCuL(H2O)](ClO4)2更稳定.

Syntheses and characterizations of macrocyclic heterodinuclear complexes [CuML(H2O)n](ClO4)2

Five new asymmetric homo- and hetero-dinuclear macrocyclic complexes [CuML(H2O)n](ClO4)2 (M=Cu,Mn,Zn,Cd and Ni,n=1 and 2) were synthesized by step cyclo-condensation reaction,where L2 is the dinuclear macrocycle with two 2,6-di(iminomethyl)-4-nbutylphenolate entities combined by two lateral chains,-(CH2)2- and -(CH2)2NH(CH2)2-,at the imino nitrogens.These complexes were characterized by some physical measurements.The species of the complexes in solution were investigated in detail by electrospray mass spectrometry.The results show that the complexes [CuMnL(H2O)2](ClO4)2,[CuZnL(H2O)2](ClO4)2 and [CuCdL(H2O)2] (ClO4)2 are more stable than [CuNiL(H2O)](ClO4)2 and [CuCuL(H2O)](ClO4)2.
