Nanoscale Homochiral C3-Symmetric Mixed-Valence Manganese Cluster Complexes with Both Ferromagnetic and Ferroelectric Properties

Abstract
Both ferromagnetic and ferroelectric properties were observed in two enantiomerically pure nanoscale manganese cluster complexes supported by chiral Schiff base ligands, each of which comprises a 22-nucleus mixed-valence manganese(II/III) supratetrahedral cluster cation and an equilateral-triangle trinuclear manganese(III) cluster anion with C3 symmetry.
