Abstract
|
|
|
|
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.
