The ligand field absorption and circulardichroism (CD) spectra were examined not only for trans-difluoro bis(diamine)chromium(III) complexes with two identical chiral diamines but also for nine new mixed diamine complexes of the same type with different diamines, which were ethylenediamine, trimethylenediamine, (R)- and (S)-propylenediamine, (1R, 2R)-1,2-cyclohexanediamine, (2R, 4R)- and (2R, 4R)-2
不仅研究了具有两种相同手性二胺的反式二氟双(二胺)铬(III)配合物的配体场吸收和圆二色性(CD)光谱,还研究了九种具有不同二胺的相同类型的新混合二胺配合物。是乙二胺、丙二胺、(R)-和(S)-丙二胺、(1R, 2R)-1,2-环己二胺、(2R, 4R)-和(2R, 4R)-2,4-戊二胺。对于大多数这些配合物,来自单个手性二胺的 CD 贡献的可加性得到证实。在此基础上,分别对由褶皱二胺环和不对称碳原子引起的构象和邻位 CD 贡献进行了区分,并结合立体化学讨论了所有现有配合物的 CD 起源。
