A pair of novel TbIII-based enantiomers,[Tb(dbm)3·LSS] (1) and [Tb(dbm)3·LRR] (2) (where LSS=(+)-4,5-pinene bipyridine,LRR= (–)-4,5-pinene bipyridine,dbm=dibenzoylmethanate),were synthesized and characterized based on single crystal X-ray diffraction,elemental analysis,FT-IR,TG and CD spectra.X-ray diffraction analysis showed that both the complexes crystallized in monoclinic crystal system with P21 chiral space group.The TbIII ion was eight-coordinated by six O atoms of three dbm ligands and two N atoms from one chiral ligand LSS or LRR.The CD spectra revealed that complexes 1 and 2 were enantiomers.Thermogravimetric analysis results indicated that 1 and 2 were thermally stable up to 246 oC.
