Crystallization of two enantiomersΔ-1andΛ-1was achieved by using an achiral flexible ligand H4L (2,2′-[1,2-ethanediylbis[(hydroxyethylimino)methylene]]bis[6-methoxy-4-methyl-phenol]). The absolute configurations of the enantiomers inP3121 (Δ-1) andP3221 (Λ-1) are confirmed by the X-ray single crystal diffraction. Solid-state circular dichroism spectra show that two enantiomers have absorption peaks of mirror symmetry. The experimental energy barrier of 88.9 K derived from the alternating-current magnetic measurements is consistent with the energy gap (89.9 K) between two lowest Kramers doublets calculated byab initiomethod.
