초록
두 개의 페놀기를 포함하는 열린 고리형태의 1, 14-Bis(2-hydroxybenzyl)-2, 6, 9, 12-tetraazatetradecane(bsated) 리간드를 염산염의 형태로 분리하여 원소 분석, 질량 스펙트럼 및 핵자기공명법으로 분석하였다. 합성된 리간드의 산 해리상수($logK^n{_H}$)와 $Cu^{2+}$, $Ni^{2+}$, $Co^{2+}$ 및 $Zn^{2+}$에 대한 안정도 상수($logK_{ML}$)를 전위차 적정법으로 결정하였다. 이때 온도는 $25^{\circ}C$ 및 이온강도는 0.10M($KNO_3$)로 고정시켰다. [Cu(bsated)] $(ClO_4)_2$ X-ray구조의 crystal data는 다음과 같다: Monoclinic space group $P2_1/n$, $a

Abstract
A new open-chain ligand containing two phenol groups, 1, 14-Bis (2-hydroxybenzyl)-2, 6, 9, 12-tetraazatetradecane(bsated) was synthesized as its tetrahydrochloride salt and characterized by elemental analysis, mass, infrared and NMR. Its proton dissociation constants ($logK^n{_H}$) and stability constants ($logK_{ML}$) toward $Co^{2+}$, $Ni^{2+}$, $Cu^{2+}$ and $Zn^{2+}$ were determined at $25^{\circ}C$ and 0.10M($KNO_3$) ionic strength in aqueous solution by potentiometry. The X-ray structure of its copper (II) complex [Cu(bsated)]$(ClO_4)_2$ was reported: Monoclinic space group $P2_1/n$, $a
