Abstract: 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. |
