네자리 리간드인 ethylenediamine-N,N'-di-S-α-propionic acid (eddp)의 디클로로 코발트(Ⅲ) 착물을 공기산화법에 의하여 합성하였다. eddp리간드는 코발트(Ⅲ) 이온에 매우 입체선택적으로 배위하여 Δ-S-cis 이성체만을 형성함이 관찰되었다. 합성된 착물의 구조는 원소분석, 적외선 분광분석법, 핵자기 공명 및 흡수스펙트럼으로 확인되었으며 특히 착물의 절대배열은 핵자기공명 스펙트럼으로 확인하였다.

Dichloro cobalt(Ⅲ) complex of a flexible tetradentate ligand of ethylenediamine-N,N'-di-S-α-propionic acid (eddp) has been prepared via the air-oxidation technique. Only Δ-cis isomer has been yielded showing high stereoselectivity of the eddp ligand. Elemental analysis, ir, nmr and electronic absorption spectra have been used to characterize the complex and the absolute configuration of the complex is assigned by means of the nmr spectroscopy.
