摘要:
用 2 ,6 -二甲醛 - 4-氯酚钠盐与三 ( 2 -氨基乙基 )胺和 2 -乙酰基吡啶 1∶1席夫碱缩合的还原产物进行 2 + 2席夫碱模板缩合 ,再与过渡金属高氯酸盐发生置换 ,合成了一系列新型的带有螯合功能臂的大环双核金属配合物 :[M2 L](ClO4) 2(M代表Mn2 + ,Cd2 + ,Zn2 + ,Cu2 + )。用红外光谱和元素分析对其进行了表征。结果表明 ,合成的产物均为预期的大环双核金属配合物。在这些配合物中 ,两臂均是从大环的同一侧与金属离子进行螯合 ,但金属离子的配位环境不同。
Abstract:
A series of new dinuclear macrocyclic complexes have been synthesized by [ 2+ 2] Schif-f base condensat ion betw een sodium 2, 6- diformyl- 4- chlorphenolate w ith the reduced 1B1 Schif f base of t ris( 2- aminoethyl) amine and 2- acetylpyridine in the presence of M(ClO4) 2· 6H2O ( M = Mn 2+ , Cd 2+ , Zn 2+ , Cu 2+ ) . T hese complexes have been characterized by elemental analyses and inf rared spect ra. The result s show that the ex pected complexes are obtained. Both arms of these complexes are on the same side of the macrocy cle. T he macrocyclic ligand of fered dif ferent coordination environments. For the Mn 2+ complex, one Mn 2+ is located in a geometry of a distorted octahedron ( six-coordinated) , another Mn 2+ is located in a g eomet ry of a capped distorted octahedron ( seven-coordinated) . It is proposed that each Cd 2+ is located in a geomet ry of a distorted octahedron, w hile Zn 2+ and Cu 2+ are located in distortedoctahedral or square-pyramidal geomet ries.
