Syntheses, Structures and Circular Dichroism Spectroscopy of Chiral Complexes [Co(L/D-thr)_3]·4.5H_2O

合成了2个基于手性配体L-和D-苏氨酸(L/D-thr)的Co髥配合物的对应异构体[Co(L-thr)3]·4.5H2O(L-1)和[Co(L-thr)3]·4.5H2O(D-1),并对2个化合物进行了单晶X射线衍射、红外、热重、紫外可见光谱以及CD谱性质研究。晶体结构分析表明,2个化合物分别结晶在四方晶系P4_32_12和P4_12_12手性空间群。固体CD谱测试进一步证实2个化合物具有手性。

A couple of enantiomer[Co（L-thr）3]·4.5H2O （L-1） and[Co（L-thr）3]·4.5H2O （D-1） consisting the Co（III） ion, based on chiral ligand L/D-threonine（L/D-thr）, were prepared and characterized by single-crystal X-ray structure analysis, IR, thermogravimetric analysis, solid-state UV-Vis spectra and circular dichroism analysis. Complexes L-1 and D-1 crystalize in tetragonal system P43212 and P41212, respectively. Moreover, the circular dichroism analysis of complexes L-1 and D-1 was measured with chirality, and the CD spectra of the enantiomer show change under the magnetic field inducing.
