Abstract
Equatorial-Skew형 [Co(TRDTRA)(OH2)]착물과 CN-, NO2- 그리고 NCS- 이온 간의 치환반응 결과 생성된 착물의 치환반응성 및 구조를 전자흡수 스펙트럼과 Yamatera 이론에 따라 조사하였다. 속도록적 자료로부터 착물과 CN-, NO2- 그리고 NCS- 이온의 반응차수는 각각 1차이며 총괄 반응차수는 2차임을 알 수 있었다. CN- 및 NO2- 이온에서 생성된 착물의 구조는 이성질화 반응이 동반된 Polar-Chair 형이며, NCS- 이온의 경우에는 이성질화 반응이 동반되지 않는 Equatorial-Skew 형임을 알 수 있었다.

The substitution reaction and structrue of products obtained from the reaction of Equatorial-Skew-[Co(TRDTRA)(OH2)] (TRDTRA = trimethylenediaminetriacetate) with CN-, NO2- and NCS- ions have been investigated by means of electronic absorption spectroscopy and theoretical calculation based on the Yamatera's theory. According to kinetic data, the substitution reaction order for the complexes such as CN-, NO2- and NCS- was the first order, respectively, and overall reaction order was second order. It has been determined that the structure of products having CN- and NO2- ions was Polar-Chair type complexes which were accompanying with isomerization and having NCS- ion was Equatorial-Skew type complex which was not accompanying with isomerization.
