거대고리 ligand와 금속 Ni(Ⅱ), Cu(Ⅱ)착물의 합성과 구조
고광오,김한아 순천향대학교 기초과학연구소 2007 순천향자연과학연구 논문집 Vol.13 No.2
In this research, the structure and coordination state of Ni(Ⅱ), Cu(Ⅱ) complexes of 14- and 15-membered macrucydic hgand(1,4,8,11-tetraazacycluteradecane, 1,4,8,12-tetraazacy clopentadecane) were investigated using the spectroscopic method. Macrocyclic ligands were purified by recrystallization. Ligands NN'N"N'"-tetra(2-cyanuethyl)-(1,4,8,11 tetraazacycluteradecane) and NN'N"N'"-tetra(2-cyanuethy1)- (1,4,8,12-tetraazacyclopen tadecane) were synthesized. In solid state, there is no interaction between Ni(Ⅱ) and the pendant CN in Ni(Ⅱ) .complexes. For Cu(Ⅱ) complex two CN bands are seen. These peaks represent the presence of free and end on coordinated nitriles.
