similar features to those of the corresponding cobalt(III) and ruthenium(III) complexes. A dissociative machanism with a square-pyramidal intermediate is assumed for these reactions. The importance of solvation, nephelauxetic, and σ-trans effects has been invoked to explain the above thermodynamic and kinetic behaviour of these ruthenium complexes.
已通过循环伏安法(cv)在水溶液中确定了一系列顺式和反式[RuL(A)X] n +类型的叔丁胺钌(III)配合物的形式还原电势E f。通常,对于给定的一对不相同的配体A和X,E f值会随着螯合的增加而增加fo L:(NH 3)4 <(en)2(en = H 2 NCH 2 CH 2 NH 2)<2 3,2-tet(3,7-二氮杂壬烷-1,9-二胺,RS异构体)
