Abstract

A straight chain flexible tetraamine ligand, 1,l0-dipropyl-5R-methyltriethylenetetraamine(R-$Pr_2$metrien) has been synthesized, and the dichloro and dinitro cobalt(III) complexes of this ligand have been prepared. The ligand has been expected to show a topological preference for the trans isomer. As expected, only trans geometrical isomers have been obtained and their structures have been elucidated via elemental analyses, nmr, electronic absorption and CD data.

새로운 네자리 아민리간드 1,10-dipropyl-5R-methyltriethylenetetramine(R-$Pr_2$metrien)이 합성되었고 이 리간드로부터 디클로로 몇 디니트로코발트(III) 착물이 합성되었다. 합성된 리간드는 트란스 이성체의 착물만을 형성할 것이 예측되었으며 예측된대로 트란스 이성체만을 형성하였다. 원소분석, 핵자기공명분광학, 흡수분광분석 및 원편광이색성분광법을 이용하여 리간드와 착물의 구조가 설명되었다.
