Abstract

The usage of the achiral ligand, in lanthanide chemistry, successfully obtained two series of chiral lanthanide complexes, formulated d‐ and l‐{Gd[IN][HIN][CH2OCH2O]}n (abbreviated as Gd) and d‐ and l‐{Dy[IN][HIN][CH2OCH2O]}n (abbreviated as Dy, HIN = isonicotinic acid). Crystallographic researches determined that four compounds are all one‐dimensional (1D) chain structures and crystallized in a chiral space group. In addition, CH2OHCH2OH acts as not only solvent but also the bridge ligand. Besides, single crystal circular dichroism (CD) spectra conformed compounds Gd‐L and Gd‐D, Dy‐L and Dy‐D are enantiomers respectively. Magnetically, compound Gd showed predominant magnetocaloric effect (MCE) of 26.20 J·kg–1·K–1 at 2.5 K for ΔH = 7 T, while there is ferromagnetic interactions in compound Dy.
