Chiral Molecule-Based Ferrimagnets with Helical Structures

Abstract

Two enantiopure one-dimensional complexes with helical structures, [Mn(3)((R,R)-Salcy)(3)(H2O)(2)Fe(CN)(6).2H2O]n (1) and [Mn(3)((S,S)-Salcy)(3)(H2O)(2)Fe(CN)(6).2H2O]n (2) [Salcy = N,N'-(1,2-cyclohexanediylethylene)bis(salicylideneiminato) dianion], have been synthesized and characterized. Magnetic studies show that both complexes are ferrimagnets with the magnetic transition temperature at 3 K.
