| Abstract: A couple of pinene-containing europium(Ⅲ) complexes, Eu(TTA)3L1a (1a) and Eu(TTA)3L1b (1b) (TTA=thenoyltrifluoroacetonate, L1a=(+)-4,5-bis(pinene)-2,2'-bipyridine, L1b=(-)-4,5-bis(pinene)-2,2'-bipyridine), were prepared and characterized. The chiral characterization was confirmed by single crystal X-ray diffraction and distinct electronic circular dichroism (CD) signals. Complex 1a crystallizes in the polar space group P1, and a strongly distorted square-antiprism environment around the Eu(Ⅲ) ion is exhibited. Due to the non-centrosymmetric structure, distinct ferroelectric behavior of complex 1a was observed as expected. |
