Sodium Ethylenediaminetetraacetatocobaltate(Ⅲ)와 Potassium Trimethylenediaminetetraacetatocobaltate(Ⅲ)Complex의 Chloride ion첨가에 관한 분광학적 고찰 = The Spectrophotometric Studies on the Addition of Chloride ion to Sodium Ethylenediaminetetraacetatocobaltate(Ⅲ) and Potassium Trimethylenediaminetetraacetatocobaltate(Ⅲ) Complex

다국어 초록 (Multilingual Abstract)

As the Sodium ethylenediaminitetraacetatocobaltate(Ⅲ) takes form five membered chelate ring, more strain is found in out-plane than in-plane. By the result of it the complex is unstable and therefore ligand, chloride ion, can attack this complex easily. But the potassium trimethylenediaminetetraacetatocobaltate(Ⅲ) form six membered chelate ring, so the structure is stable. As a conseguence of the above, the attack of chloride ion as lignad is found to be difficult.
