| Research Abstract |
In this study a novel crystallization phenomenon, namely complete spontaneous resolution, has been studied. When some kind of metal complexes bearing organic ligands without any asymmetric centerwere crystallized in a certain condition, either of an enantiomeric pair was always obtained specifically. Trinuclear transition- metal (TM)-lanthanide (Ln)-TM complexes with two tripodal potentially nonadentate Schiff-base ligands or mononuclear TM complexes containing a tripodal imidazole-derived Schiff-base ligand exhibited such an interesting phenomenon. Also, it was found that a choice of TM and Ln metal ions and that of recrystallization solvent are critical for this phenomenon. At this moment, the origin for complete spontaneous resolution or the outbreak of optical activity of chiral compounds are still veiled, but we have established this fascinating phenomenon with finding examples of high reproducibility.
