A homochiral magnet based on D3 symmetric [(NaO3)Co3] clusters: from spontaneous resolution to absolute chiral induction

Author affiliations

Abstract

A pair of novel enantiomeric 3D magnetic complexes [NaCo3(IA)6](NO3)·H2O ( and ) have been synthesized using an achiral ligand HIA via spontaneous resolution, which crystallize in the hexagonal crystal system with a chiral P63 space group, and diamagnetic sodium cations are located at the center of D3 symmetric clusters. This kind of spontaneous resolution is uncontrollable and dependent on batches. By utilizing cheap enantiopure mandelic acid as a chiral inducing agent, they are driven to controllable homochiral crystallization of the desired enantiomorph, confirmed by circular dichroism spectra.
