complex gave only two isomers of merΛ-(lel3) and fac-Λ(lel3). Two isomers, Λ(lel3) and Δ(ob3) of the [Co(S,S)-2,3-butane-diamine}3]3+ complex were obtained. The formation ratios of these tris(1,2-diamine)cobalt(III) complexes were compared with those of the analogous complexes and discussed. The tetraammine complexes of all those diamines were also prepared. Absorption and circular dichroism spectra
[Co(R)-
1-苯基-1,2-乙二胺}3]3+ 复合物产生了所有四种可能的异构体,mer-Δ(lel3)、mer-Λ(ob3)、fac-Δ(lel3) )和fac-Λ(ob3),而[Co(S)-3,3-二甲基-1,2-丁二胺}3]3+复合物仅产生merΛ-(lel3)和fac-Λ的两种异构体(lel3)。获得了[Co(S,S)-2,3-
丁烷-二胺}3]3+复合物的两种异构体Λ(lel3)和Δ(ob3)。将这些三(1,2-二胺)
钴(III)配合物的形成率与类似配合物的形成率进行比较和讨论。还制备了所有这些二胺的四胺配合物。记录了所有配合物的吸收光谱和圆二色光谱。
