R(-)-2-methyl-1,4,7- triazacyclononane and its cobalt(III) complex [Co (R-MeTACN)2]3+ is reported. The complex is found to exhibit in the 480 nm region the largest ring-conformation d-electron optical activity yet recorded for the [CoN6 chromophore, due to a chiral puckering, with the λ-conformation, of each of the six chelate rings. The c.d. spectrum of the complex is found to be consistent with the dynamic
摘要报道了配体R(-)-2-甲基-1,4,7-三氮杂环壬烷及其钴(III)配合物[Co(R-MeTACN)2] 3+的合成。由于该六个螯合环中的每一个都具有λ构型的手性起皱,发现该络合物在480 nm区域显示出最大的环构型d电子光学活性,但仍记录了[CoN6发色团。发现该络合物的cd光谱与d电子光学活性的动态耦合模型一致,但与相应的晶体场模型不一致。
