四氮唑三核Cu(Ⅱ)配合物的原位组装及其结构研究

IN SITU SYNTHESIS AND STRUCTURE OF TRINUCLEAR TETRAZOLE Cu(Ⅱ) COMPLEXE

原位法合成了一个结构新颖的四氮唑三核Cu(Ⅱ)配合物[Cu3(sae)2(mtta)(N3)](mtta=5-甲基四氮唑,sae=水杨醛缩乙醇胺),用X-射线衍射确定了结构。配合物[Cu3(sae)2(mtta)(N3)]是由5-甲基四氮唑和水杨醛缩乙醇胺(希夫碱)混桥联的三核铜配合物,5-甲基四氮唑是室温条件下在体系中合成的。在配合物中希夫碱和四氮唑都为三齿配体,与三个Cu(Ⅱ)原子配位,配合物中每个Cu(Ⅱ)离子均为4配位,两个希夫碱和一个四氮唑几乎处于一个平面,可看成一个畸变的平面四方形结构。

A copper（Ⅱ） coordination compound,[Cu3（ sae）2（ mtta）（ N3） ]（ mtta = 5- methyl tetrazole,sae = N- salicylidene- N＇- aminoethanol） has been synthesized and characterized by single- crystal X- ray diffraction. 5- methyl tetrazol and N-salicylidene- N＇- aminoethanol（ Schiff base） was the mixed- bridge of compound [Cu3（ sae）2（ mtta）（ N3） ],and 5- methyl tetrazole was synthesized at room temperature in this system. The Schiff base and the tetrazole coordinated with three Cu（Ⅱ） ions,and each of the Cu（Ⅱ） ions was 4 coordinated. The two Schiff bases and a tetrazole are nearly in one plane,and this plane can be known as a distorted tetragona.
